HT system
If you do some reading on the forum, I think you will find several better performing options than the bose 3-2-1 system.
If you want something simple to setup, like the bose, and only need 2 channels, then check out the Denon S-101 system. Note, that unlike the Bose you get a subwoofer in addition to the two speakers.

If you have a small to medium size square room, then the Yamaha YSP-800 might be a good option. The YSP will simulate surround sound and can be directly connected to DVD and other audio inputs.
If you don't mind a little wiring and setup then you should consider a 5.1 speaker system with an entry level receiver and DVD player. In you budget, BIC or Athena bookshelf speakers and an entry level Yamaha or Onkyo receiver would be a good combination.
Post your budget, room size, # of speakers (2.1, 5.1, or 7.1), and the number of components you need (speakers, receiver, DVD, etc.) and you will get more specific recommendations.
