I considered the 220 sport, custom 1911, and the USP match a while back. The match is a discontinued gun. It has a front barrel weight, which has the word "match" printed on it in this goofy blue font. It is not even a compensator. It feels like a big plastic gun with a piece of aluminum in front. The trigger is very USP-esque, which I don't really like, even though it has a trigger over-travel stop mechanism. If you love the USP, I think getting the newer expert makes more sense.
The sig 220 S is the choice I made in the end. It is truly an amazing gun that shoots ridiculously well. Trigger is very smooth, and the kicks very little. The compensator looks like an afterthought because it is a different shade of silver than the rest of the gun. The gun looks huge, and is very easy to hold steady. Accuracy is unbelievable with Fiocchi target ammo, which runs <$200/1000. I got my gun through CDNN as thequickad pointed out. By the way, the 220 sport "feels" like a completely different gun than the standard 220.
Accurized, compensated custom 1911s are beautiful guns. But $850 won't buy you much.
