Do you have a center channel? That's what I would get for $200.
Otherwise, I would save up a little more and get a good sub (you can get a nice sub around $500 from SVS or HSU). Maybe consider a less expensive receiver and put more money towards the sub (check the panasonic xr55). A good sub is very important for HT. You can get away with decent speakers if you have a great sub, but you won't get away with great speakers and a lousy sub for HT, IMHO. Unless your mains are nice full-range floorstanders or they're crossed at 50Hz or so. Or, unless you primarly watch subtitled, drama, love stories. Cheap subs are boomy and just make noise. A good sub will blend with the speakers and produce bass that doesn't sound like an 808 drum everytime under 40Hz.
The only sub I would consider for your price range would be the Dayton 10" or 12" because they are priced so well, but they are backordered till after the new year. I've also heard good things about the Acoustech sub, and some of the BIC subs. I believe there's a 10" mirage at vanns.com for $250 which looks like a great deal, and gets good reviews. Personally I would save up and check out the SVS or HSU. Or build yourself a sub.
Good luck
