hmm, how high are we talking about? Probably my sterling stp or the polished classic mag, with intelliframe I traded for it. That was back in 2005 maybe? so they both were worth a bit more then. I got a micromag, so that was a bit of a step up from the previous mag, though I wish I still had the intelliframe.
In the past year I picked up a 2k rf cocker, middle of the road, but shoots probably the best and most consistent out of all my guns. Also a 1kBlazer, just needs to be tuned for consistency.
Probably none of these were ever considered high end other than the blazer.
