I've purchased almost all of my Busses directly from Busse or from the long-defunct (and sorely missed) Busse Company Store. For the direct-from-Busse blades, most have been ordered from the website, but a significant minority have been offered on this forum through "Ganzaaas" (basically an online free for all where a few knives are offered on a first-come-first-served basis). I've bought maybe half a dozen off the
Exchange, but tat's just a drop in the buclet.
Busse's been playing catch-up for the past year after offering one or more new knives per week in "Operation Two Weeks" (a/k/a "O2W"). They still have 10 varieties from O2W that were ordered about a year ago and that they haven't started charging people's credit cards for yet. Jerry has said that they'll be back with O2W Part 2, but when is a little murky. They'll
probably be finishing up with the O2W Part 1 blades sometime after the Blade show (June 2-4 in Atlanta), and then we'll
probably start seeing new models available on the Busse website and maybe on this forum.
In the meantime, there are lots of things avaiable here on the Exchange. Most asking prices will be a bit higher than the original release price, but histoically most Busse knives have appreciated, and even used ones will often sell for more than their original price. With the flood of new models in OTW (and people maybe buying more than they otherwise would have), the aftermarket is still relatively depressed, and prices on a lot of things are relatively low right now compared to what they have been in the past.
Prices on eBay are typically higher than what you'll find on the Exchange.
