Get the CG. And don't look back, for the money the quality,warrantee and service can't be beat, sure you can spend a lot more, checkout the new prices for a Seitz,Ljutic, Perazzi, k-80 etc.check what a used one is going for you'll see how their resale value is , spend the extra money saved on ammo and practice, practice,practice.
I've had my Summit for three + years now ,ZERO problems, most of my buddies shoot Ljutics,they've have more than their share of problems,ribs, triggers, forearms etc. these are 7-8 K guns, My CG just keeps on ticking.
Seitz are fairly numerous too,the guys don't put a lot of rounds through them though, (when you've got 4,or 5 of them though they don't get a lot of use, beautiful guns, for 14K they'd better be) the choice is yours, hope this helps. I'd buy another CG. In a heartbeat. Breakemall ML.
