You might want to check gunbroker.com and target talk in U.S. Try to find a baikalIZH46M, they are competition grade single strike(no CO2 or air tanks) You can get good used for 200.00 to 300.00. They last forever, and as accurate as any Olympic air pistol. With one of these you are ready for regional airpistol matches at least. They usually come with spares, tools as well.

I would go with the HW40 in 177 for about 200 bucks. Its simple accurate and excellent resale value.
Sold at Canadian tire as the Beeman p17 for $99.99, with a red dot mounted!
