Normally, I would have suggested scondhand and this was was the route I went down last year when looking for a nice HW98...but people were so unrealistic on their prices or wanted to sell a package (usually including a scope I didn't want - "it'll sell easy mate"...well, if it's that easy you sell it!!) that in the end I bought new locally - even better when they gave me about 12% off for being a member of a local shooting club and a pack of free pellets as well..
It only cost me £20 more...lovely jubbly all shiny and new, warrantied and saved any hassle with travelling.
So don't discount new ones...
