Shipping is only $10 from CDNN plus a couple bucks for signature confirmation. I believe you can also add some accessories to the order without incurring additional shipping charges.
I haven't fired enough CZs to really review the trigger. The DA trigger is smooth enough, but I'm really only ever carry the pistol in SA. If you really milk the SA trigger, you can feel a bit of scritchyness, but it's so short and light, you don't notice.
I don't have a still camera right now, so I can't post a pic. It's really not that badly beat up, but it's evident that the nicks are from abuse rather than normal wear and it drives me nuts that someone might see them and think I'd treat a weapon like that. It may make a journey to Virgil Tripp's and get hard chromed.
I don't have real strong feelings about the trigger guard either way. I do think the round trigger guards look classier, but the current squared style is easier to find leather for.
I'm also not sure what to tell you about the safety - it has a nice positive "click", but I don't experience anything like a weird detent. When I picked it up, the nooks and crannys were full of cosmo, and the safety was a little sludgy. A good blasting of Gun Scrubber and a spritz out with G96 and it's smooth and crisp now.
