i bought my 1050 used 'bout 1 1/2 years ago,i love it,no problems.i power my center and surrounds with it(and don't have to) i do mostly 2-ch listening.$375 is a good price,they have held their value,unlike the competition.
i'll use it till it dies!

not familiar with the yammie,though.

outlaw is the best buy,they have great customer support,and an awesome SALOON!most problems get solved right here.
