The 270 seemed like a very simplistic receiver because...it was. I think the last I saw them new they were $189.00
I think you are going to be disappointed with anything in your price range, based on your requirements, whether it be Denon, Yamaha, Onkyo, etc. AVR prices are pretty much driven by features. You know, like at the bottom end you may not even get Audyssey, then for a few hundred more you get the basic 3 position, then all the way up to the 32 position version. I think those receivers start at about 1k.
There are some good open box or factory reconditioned deals to be had, or if you aren't too worried about used, you can pick up a couple year old model that was $1200.00 list for around $500.00
What type of speakers and sub do you have?
As well, I don't think you have to bump the thread after 12 hours.....if you read this forum, there are at least 10 questions identical to yours in the first 5 pages.
