Just the light modifiers themselves? $200 should be well within the ballpark. If you're looking for lightstands, swivels and something to fire your strobes with, you might be out of luck. Check out strobist.com for some good, basic lighting setups.
For low cost decent quality I found the Calumet house-brand stands and umbrellas to be very good. Should be in your budget range. For softboxes I went with the "Promaster" branded kits sold here locally through Hunts photo & video. Kind of like Lastolite knock-offs.
