Still seeing them regularly - however the original S&Ws are going over the top in price. You can expext to pay anywhere from about $1500 for a beater, to $5000-$6000 for one in pristine condition. These are the big bore single actions. The smaller calibre .32 and .38 S&Ws are more reasonable ($500-$1000) in execellent condition depending on the model. www.oldwestgunsmith.com is a good sight to check.
Uberti is making top breaks for the SASS crowd and those who just like an old west classic. However when they were designed this go-round, to accomadate longer cartridges, they took the gas ring off of the cylinder. This makes them a smokeless powder cartridge gun only. The black powder fouling will bind them up after a few shots. Uberti is making them for several vendors such as Navy Arms... The Ubertis are going between $750-$850. Beretta has also bought Uberti and is putting out a top break under their name that is a little higher in cost.
S&W re-issued the Schofield in 2000 (limited edition), and they are all over the internet for around $2000. They are chambered for the .45 Schofield only which can make shooting a little pricy for the average person.
