Seriously!
In case you're wondering what the hell I'm ranting about, let me fill you in...
I just bought a set of monolights from Calumet. They're incredibly cheap, but they feel pretty solid, have a decent set of features, and use a reflector mount that fits accessories from one of the top strobe manufacturers in the world, Elinchrom.

The two kits I bought.
Not exactly Profotos, but it's hard to beat that price!
I purchased two separate kits, 1 kit with two 400ws lights and 1 kit with two 200ws lights, for a total of 1200ws of lighting split between 4 heads. I got all four lights with light stands and four 45" umbrellas for less than $1000, which is a steal by studio lighting standards. The lights have their issues and are definitely a little under powered for some professional work, but they cost me less than a grand! Besides, if I book a big job, I'll most likely be using rental gear anyway, in which case, these little lights would make pretty decent backups to some quality rental gear. Despite their lesser qualities, these guys are perfect for more relaxed, low pressure, portfolio shoots and small space location work. Think headshots in some ones apartment, house, or office.
These lights use an Elinchrom mount for accessories like reflectors, speedrings (for softboxes), grids and beauty dishes. Elinchrom is a manufacturer of some top quality lighting gear, which is both a blessing (great light modifiers) and a curse (they're very expensive). So, I've been pricing some of the above mentioned accessories to see how much my $1000 light kit will set me back for some good modifiers.

The Elinchrom Octa Light Bank, $1100... Daaaamn!
That's more than I paid for all 4 lights with stands and umbrellas.
During my research into the world of studio lighting, what amazed me most, was how expensive some of these items are. I mean, how can anyone justify paying $1100 dollars for an octagonal shaped softbox? I know that it creates really nice light, but $1100... really? It's just a big, fancy, reflective umbrella with a diffusion silk in front of it! I also find it hard to justify paying $250 for a decent 'regular' softbox; it's just a bunch of reflective fabric, some wire frame, and a translucent silk! (a tent for my lights to go camping, how quaint) $250 for a medium box is pretty rough, but $1100 dollars for the same thing except bigger and shaped like a stop sign... come on, it's ridiculous! As an independent business owner, I appreciate the need to add in the costs of R&D, marketing and a host of other administrative duties that most people can't or don't undersand about running a profitable business, but $1100 for a big octabox is pretty ridiculous no matter how well it's made. I can justify the "some" of the high cost of premium lights, but is it really necessary to gouge us consumers with the smaller, lower production cost items?

Since Calumet was nice enough to design a light that doesn't allow 7" grids to be used when the modeling light is in place, my only real option for a grid set costs about $200. Damn you Calumet, whyyyyyy!!!

$155 for a big pan; but oh how nice the light is...

Really, a metal ring with a few screws costs that much?
Luckily, since speedrings are pretty common items, there are a few low cost options for obtaining one.
Actually, I bet most of these companies make more 'profit' on softboxes and umbrellas than they do on their lights. Fortunately, I may have found a decent replacement for the octa-bank in question. I'll be sure to post more info once I'm sure that the supplier is reputable and the equipment is of decent quality.
I know that there's some truth to the phrase, "you get what you pay for." However, just because something is expensive, doesn't guarantee that it's high quality and even if it is, that doesn't mean that there aren't better 'values' out there. When I deal with potential clients who question my rates, I try to point out the 'value' I bring to the equation. I consider the same thing when buying photography equipment; value, not just price! In the end the only thing that really matters is what works for you and your specific style of creating images and what you 'value' when looking for equipment.
