Here's a scale shot I took of most of the Star Wars lines.

From left to right, WOTC Metal, WEG, Imperial Assault, WOTC plastic and Knight Models. The WEG doesn't even come close. On the other hand, if you look around on E-Bay I know there's a guy selling old, badly painted WEG figures in a lot at around a buck a piece. I know this because he's selling them for me. Look around for a while. There are deals to be had, as long as you're willing to strip paint, or live without the blister cards.
And the best quality WEG minis are the ones in the box sets. Those came out before the blister packs. At least that's how it was for me.
