Sentinel,
Unfortunately, you are asking for too much in a small price range. If you want what you pay for, then LG/Samsung/Onkyo are the only packages that you may be able to find. Samsung has floorstanders in their range but their performance is limited. Look at Audiocraft/Craftel (search the forum for their contact information) or DNM for budget 5.1 avrs. They may be able to put together a custom system for you, within your budget. Maybe.
If you want exactly what you pay for, then you're not going to get much. Take the advice of forum members here and build up your system one step at a time. Go for good bookshelves with a good stereo amp, see how it sounds with your music and movies. Then go for the rest of the system after you understand what your needs are. I've gone down this road before where I had a limited budget. Buying everything at once is always suboptimal and inevitably leads to regret somewhere down the road.
