Whats the difference between the AVR-887 and the AVR-2307?

Looks like they are the same except for the CI on the 2307, which is Denon's name for being custom-installable. So it has Zone 2, 12v triggers and RS232 port for $100 more. The 4-digit Denons are the high-end line, the 3-digit are for sale at stores like Best Buy. But the 2 lines do cross over and have very similar specs for some models.

Well, I guess I only need the 887 then You guys just saved me $100!

What I do is find a friend to sell these to. I usually sell for whatever the lowest current eBay price is. It made it easier into my second receiver and third HDTV.

A quick note for anybody that does pick up the Denon 887 and maybe you won't feel as stupid as I did. I hooked it up (feeling very overconfident in my abilities to correctly get everything right the first time without instructions) and thought I had it all installed perfectly. I plug it in, hit the power.... nothing. Try a different plug... nothing. Try the remote, the harmony remote, other rooms... not a standby light in sight. So after I've disassembled the entire thing to move it around, I decide to bust out the instructions which go on to show that there's a very small standby button underneath the power switch that is set to 'off' and you must turn it on to get power. Sometimes, I'm just an idiot.
