I really want a premier scope. I've found a few for sale but after researching, have noticed a lot of guys saying the parallax can get ruined by too much torque on the rings and with no warranty...would I be a fool at this point to even purchase one? I'm not going to be dragging this thing over mountains and beating the piss out of it. But I really dont want an $1800 paper weight. Is it pretty much general consensus now to just steer clear of them? Or should I be ok?
