The XS19 looks like it is a copy of the Gamo.I had an SR2 for a few years when they first came out and mine was pretty good once i got used to it's quirks. The quality was not the best but a vast improvement to the B2. Putting my HW80 next to the SR2 you could see that the quality was not in the same league but at £139.95 you can't expect it, The SR took a battering in the rain and mud of winter and it was totally unloved. I would never bother with another but give them their due if you are lucky to get a goodun then they can be a good buy for the money.
