I think they are still $16 at bi-mart last I lookedMy grandather was the original user and "supplier" to my fathers generation and mine. Must have been in the late 70's to early 80's(?). No idea what he was paying back then, but when it fell to me to be the new supplier for the third generation I seem to recall paying something around $13(?) or $17(?). Seeing they are running around $20-ish today... I would say that's one bubblegum of an incredibly good deal for what it's capable of. I dunno if the steel is the same these days (noticed they do one in SS now, too), I would have to do a search on that, but considering the 5th generation will be ready to start earning theirs within the next decade maybe it's time to pick up a few before they can't be had of any similar quality any more.
Either that or start recycling those previously owned by those who have retired to the great hunting grounds.
