just my .02, I bought my first CZ from CZC - a CZ75 Shadow that is just awesome at the time they were roughly $1300, since then I have bought a CZ75 Compact which was box-stock straight from the factory without any work for under $500, If I had it to do over again I am not sure I would buy the Custom model - maybe I am just too ham-fisted to tell the difference but the trigger on the compact is almost as nice as the custom and I am not sure if the difference in price would be worth it to me again, but YMMV
This isn't to say that CZC doesn't do great work, because they do, and I still want to get one of their short reset triggers put on each of mine
