$200 for the pair, or $200 each? You can get a pair of
KRK Rokit 6's for about $400:

I have the truth's, I like em. 8" active monitor, can't beat em for the price. I never heard anyone complain about krk. Yamaha is nicer in general, but
the hs50m's are only 5".
If you need the pair for $200, then I dont really have any advice for you, thats a pretty limiting budget. Google around, see what's available on zzounds, musiciansfriend, samedaymusic, etc. Find reviews, etc. I saw some stuff by M-Audio, behringer, and other mfr's I never heard of, you'll have to research reviews, do some research.
The connection shouldnt matter, you can get adapters for convert any jack/plug to whatever you need.
