I had a MkII a while back and sold it when times were tough. I recently picked up a Buckmark and have been very happy with it. I never really got the hang of disassembling that Ruger, the Buckmark is a more straightforward affair.
If you go the Buckmark route, do the "Heggis Flip" mod. It lightened my trigger pull significantly and has been flawless for ~2000 rounds.
