Go Truespace!
Fly be free! . . . .
I model in Truespace 3, i'd use 2.1 but I lost my cd. I UV map with lithunwrap
i also use lithunwrap to export to 3ds so I can generate glowmaps and tweak geometry in max 9 32 bit.
I texture in flash and tweak in photoshop and PSP7 
Hm... you DO know tS7 is free by now?

(advantages: add edges, polygon draw, an uv-editor,
nearly working booleans [in model space, at least] , ...)
Anyway - I started in 2001 with Blender, got clipping issues (2 models) and messed up models (2 other) back then. Re-built the messed-up models in tS (v2 at that time was free, as far as I remember) and stuck with tS from then on (bought v4.3 and v6.6, currently using the free v7.6 - I just recently saw there's an 7.61 by now).
Nothing against Blender - either I did something completely wrong back the, or it was just some bugs that'll presumably have been solved by now, but by now I got used to tS's interface, so...

I also had GMax at some point, but somehow didn't find a way to convert to FS and thus didn't even really start with it...
Else then that I'm using UltimateUnwrap v2.xx for editing UV's - though the uv-editor in tS7 ain't THAT bad, either.
And for textures several different programs... I once wanted to try GIMP, but somehow I didn't find my way through it's interface...
