Its personal ofcourse, but I never liked the FWB's. Dont like the cocking, and dont like their backwards balance/weight.
Allthough they áre great shooters ofcourse.
I dó like the Tau 7! A LOT!
They're GREAT pistols!!
But if you want self contained, look at the Diana 6M/10 pistols. Same age as the FWB's, but I like their shooting behaviour better. And their cocking too (breakbarrel). Same as I prefer the 75 above the 300. Same system of anti-recoil.
IZH also has a very nice SSP pistol, the 46. Very good too. An old FWB100 SSP will go for about the same $$.
But I dont like the reverse cocking of SSP's. But they shoot VERY nice, completely recoilless! So, find out what powerplant you like first.
Good luck with yr choice.
By the w, there's a Tau 7 on egun.de at the mo.
