I'm fond of the single actions myself, and i definitely have a weakness for old Browning Hi-Powers. Maybe obsession is more like it, i currently have 25.
Oh man me too. Its almost spiritual
A couple years back I checked out the Colt Single Action Army but $1380.00 was-is waaay out of the budget. And their new Cowboy model is pretty good too and was +/-$680.00 and felt almost like the SSA. The Ruger Vaquero was about $100.00 less and not bad but it's a little thicker in the grips.
There's a few other brands now too, like US Firearms and Cimerron and Beretta makes a single action also. Cowboy action shooting is a fast growing sport.
I have my list for when I hit the lotto :-)
