You might want to try going to different BB/Magnolia's in SD and look for closeouts on the omnisat V2's (almost identical to OS3). I bought (new and sealed) 4 V2's and a V2 CC for $350 about 10 days ago.
Bought and returned the Omni 150 5.0 package from Vann's. Great sound, but much larger than I preferred.
Bought and returned Take classics, lacked too much in midbass and high's were mediocre. Decent speakers for price, but the upgrade bug will hit you sooner than you think.
Bought and returned TSC's Tsat 5.0 package. Great sound for sat's. Nice crisp high's, but not much midbass just as with all satellite speakers. However, a decent sub can help alleviate this shortcoming.
+1 on the energy esw-V8 for $250. Bought from WWW.stereo
and more than pleased with this for HT and sounds great with music!
My reccomendation would be as follows:
1. hunt for the mirage V2's. Rates about 9/10 on the HCF (Hot chick Factor) If that doesn't pan out then...
2. Buy the TSAT 5.0 from TSC. Good sound and rates 8/10 on the HCF.
Either way, get the ESW-V8 for 250 shipped. it's a no brainer.
Hope this helps, good luck
