I have a 100s and it's fantastic, i purchased it second hand and have not regretted it one little bit. It's a tad heavy when i've got it up for a while but it's solid and you know it will last and last. Accuracy is great 10 shots in 10p @35yards no problem, it's fairly quiet, cock's very nicely etc etc. I've used mine for bunnies, rats, birds and the like and love it. The only reason i'd ever think of changing mine is for a lighter rifle, but i don't think that the pro of that would outweigh the cons, i've used 410's etc etc and i'll stick to my HW100 thanks :-)
