Are the "experts" at best buy lying too me again ??

Ok here is my question, My wife and I just built a house that was prewired for 5.1 surround sound. I have a 52" Samsung 1080p tv with a sony bluray stand-alone player as well as a PS3. I have an older sony receiver that has dolby 5.1 but has no HDMI jacks what so ever. Have the bluray and directv box hooked up with digital coax and optical respectively since I only have one of each. Now comes to my question. Obviously when it comes to home audio, you get what you pay for, we all know that. I was looking at several reveivers at Best Buy in the $3-400 range. Alot of them have at least 2 HDMI in and 1 out, which would be perfect for me. Again the "expert" at Best Buy stated that the receivers in that price range (Sony, Denon, Yamaha) would not do what I want because I need an 800 receiver or else it wouldn't allow for 1080p and that I would not get audio, only video. I've looked thru alot of posts and haven't seen an answer. Sorry if I might have missed it. I would of course LIKE to have a real nice expencive receiver, but having just closed on the house 3 weeks ago, if I brought something like that home it better have a box big enough for me to sleep in, cause thats where the wife would put me. Y'all helped me out and saved me tons of money on HDMI cables so I thought I would fire this off and see what kind of advice you could give..THANKS !!
