gameSpace light is pretty good. Rather buggy but easier than milkshape IMHO. Just save your work every few steps of the way and you'll be fine. gSl is free. milkshape is 20 bucks. I didn't like how in milk shape I constantly had to click the button over and over again to do something that should be continous.. It became very prohibitive.

But to each his own, just offering my advice.
