I am considering a Tech Force air rifle. I have read good things about them in this forum. I have narrowed it down to models 34 and 97. The 97 cites 900 fps in 177 0.15" c-t-c groups @ 10m Price w/scope $120. The 34 cites 850 fps , no grouping mentioned, price w/scope $60. Both are fixed barrel, underlever models. Does anybody have any experience with either model. They seem very close for difference in price.
