Depends on your budget.
If you have the time to wait, go with the Milt Sparks Versa Max 2.

If ugly isn't an issue,
take a look at Crossbreed.
I heard everyone talking about them but never could see the value. Leather + Kydex + sheet metal belt clips???
That was until I broke down and bought one. I can wear a Government 45 all day including sitting and driving in real comfort! Their ads say it all, "Crossbreed just works!"
