What's the best 5 channel for less then 1K?

If you are doing A/V, I would recommend picking up a used Anthem MCA-5, they tend to sell for about $1k used. The Anthem MCA amps are 200 watts/ch. which will give you more than enough power should you decide to REALLY rattle the walls. It's not a bad amp, I own an MCA-2 for my secondary system. I'm very pleased with it.

I use an Acurus 125x5 for HT and find it excellent. I paid about $850 for mine but have seen them advertised here (used) for $600 or even less. At that price, it would be a steal. Very solidly built, very heavy, very reliable. I think there may be a 200x5 available too, but the 125 is perfectly adequate for me.

I agree with the anthem recomendation. I would also suggest taking a look at a used ATI 1505 150W x 5, you could probablty get one for 1100-1200. I own the ATI and really like it. I have had parasounds and the lower end parasounds are only average as with the Sony's.

The BEST multi-channel amp for anywhere near that price is the EAD POWERMASTER 500. You will not find a more musical mulit-channel amp......possibly at all! this amp is UNREAL! Power-steering feature in 2 channel will direct power-on-demand to the speakers that need it most. Some say they have had upwards of 450+wpc into a single channel in stereo listening. the looks are very high-end also, much better than the other amps mentioned (IMHO). They usually are sold on audiogon for between 800-1000$$$. GOOD LUCK!!

Used Parasound hca-1206 for 700 to 800 used. Built like a tank, six channels (135w > 8 ohms, 200 > 4), four channels are bridgeable (making 350 watts) and that leaves a pair of channels for a set of stereo speakers in that configuration. And, a very useful item; each channel has its own output control. This is quite practical when most AV preamps only have 1db channel setting increments. The amp was designed by John Curl and sounds very nice for a high powered mid priced solid state amplifier. It is simply at steal at 700 used.
