Amp reccomendation........with a weight limit??

So I'm trying to buy a decent sounding amp that will go well with my BG corp radia Z-92 towers and Z-62 center.

the only twist....unfortunately I have a weight limit of 80 pounds per package..... which was leading me to side more with monoblocks since a good majority of the decent stereo amps goes into the triple digits.....

oh, and i don't own a preamp or cd player yet since i'm kind of reverse engineering this, the speakers and amps being the heaviest components and all....

any reccomendations are welcome :)
