If it is not available, Rockhopper Audio makes and sells them regularly, but the above link is a particularly good price.

Hybrid MiniMAX and CKKIII are both less than that price point, have a small footprint and perform/sound quite awesome. M3/PPAv2 with a wallwart is also a good alternative. You aren't going to find any other amps that will match them at that price bracket.

I am not that handy.

I wish I could build one but I just don't have the skills.
