I've had a few WE 1911s and liked em. I have a WE DW4.3 and have mixed feelings about it: it's okay but needed work (dremeling) to get running smoothly, new inner barrel, spring set, piston head. I definitely wouldn't pay $300+ for it.
Your comment about "carbon fiber": wtf? TM guns are ABS.
In a similar size and all metal, one clone I've been extremely impressed with so far is the HK3 PX4. Impressed enough that I thought it deserved the ³H sights.
