A Galaxy 959 is not a good radio to do these kind of mods to. Poor quality control, drifty SSB and poor receive (white noise).... this kind of stuff makes me glad I run the old CB equipment. But then again, I'm real old school with my thinking, just do a good alignment, put in a few channels (no channel boards, etc), unlock the clarifier, and call it a day. If I need extra power, I just get an external amp. I couldn't ever justify spending $500 for something like this 959 when I can get a good 1980's AM/SSB mobile PLUS an amp for half the money.
W9CLL is right on the money with his suggestion for an Optima MkIII. 40-50W of SSB power, drift free on SSB, good noise blanker circuit, compact size.
Sorry that ya feel you got ripped off, but hopefully you'll see that the new stuff isn't always better!
