Nope I'd buy more, it's an amazing knife, it's really too bad they haven't started bringing some of the premium steel editions into regular production as it appears some other companies are starting to do (BM 940-1, ZT 562CF, 620CF, etc). The secondary market prices are ridiculous on the sprint/limited edition PM2's. It speaks to their popularity but sadly it creates a lot of people and no doubt some dealers pre-ordering/buying them all up with the motivation only to resell for prices way over MSRP. Just look at the same sellers with sprint PM2 or mule after mule for auction on Ebay. I just won't support those practices, it's really kind of soured me on the whole sprint/limited edition knives, and not just from Spyderco.
I'd say the same for the Mule series, while the concept was a risk and amazing at the time, and kudos for Spyderco to go out on a limb but I think that model has proven by how fast they are bought up and put on the secondary market at 200+% markup that the market would easily support a much larger regular supply even at full MSRP.
I don't have a good solution for it aside to increase production numbers to catch up to the demand curve.
