Best surround processor $2-2.5K used ????

None in my opinion! I've read all the reviews and they coincide with my experience with the NAD T175 -- there simply isn't an HDMI processor on the market that I know of without any problems (popping noises, hdmi handshake, etc.). Bet best is to pick up a used Onkyo Integra DTC-9.8 for about $800, and wait for something like the NAD M15HD to start showing up on the used market. I personally just bought a NAD M15 and am going to use analog outputs.

Maybe some people could tolerate operational quirks better than I can...

Pick up the Mcintosh MX132 used on Audiogon now, Get a HDMI switcher..Run the Audio thru good audio cables.

Great Price Fix.

Ther's an MX 134 and MX 135 available used now also

I am on my second hdmi rec. My first was the Onkyo 875. It ran HOT,HOT. but who could complain about doing hot dogs and marshmallows in your living room.? It failed within 4 months.---BUT,before its demise it sounded great for sure. Then I bought the Denon 4308ci. It has had no problems of any nature. I honestly think the Onkyo sounded more dynamic but reliability counts too. I use my main front amp for the fronts.--They all have pre-outs.---Re. the "handshake" or other issues---I have experienced NONE.-----BUT--- I wouldn't buy a used one. The differences between a rec. with an outboard amp and a processor aren't as huge as one might think. Not to mention the extra amps/wires and clutter.
Sure; I understand those that want the best wouldn't want my solution.

Thank you all.

How does a HDMI switcher work? I also heard of a HDMI card. Are they the same as a switcher?
