Usa2100 or Usx2150?

[Ne1 0]

I am curious to know which of these two amps you all would consider to be better made? Here's my dilema.....I currently have a USA2100 in my car, and working fine. My speakers can handle 150 watts rms (Diamond audio's) I just sourced a USX2150 (no lightbar) also made by Zed Audio. IT works....sorta. one channels out, and the output of the other one is weak...definetly heading south. Is the USX2150 that much better of an amp to warrant getting it repaired, or should I just stick with the 2100, and then spend my money on locating a good 2300 for my subs? Or get the 2150 repaired, and then start looking for a 600f or 800f? How much would repair run on a 2150 anyways while we are on the subject...., if anyone knows....

Thanks~!
