R10s are better when they have had the reg replaced, otherwise they are a well documented time bomb HW100s are decent guns, but 2 out of 3 of mine leaked, and they all seem to need work sooner rather than later. Another for the mix would be a Regal - multi shot, very accurate, about 80 good shots, lightweight, very good looking, nothing really goes wrong with them other than some early ones had stiff bolts which Daystate sorted, so you should not fine any of those now anyway
