A great choice. Ignore the doom mongers �� and see how yours shoots before jumping straight on the strip it immediately band wagon. You may get a good one. If it is a bit jumpy but not graunchy get a tin of pellets through it to bed it in. The first quick and easy tuning tip I would try first is to roll up some lead flashing and substitute it for the silencer internals (making sure that it lets the pellets through the middle of course!).
Rich.
