Haha, there's
a Konix Speedking on Trademe right now. The buy now is naturally completely out to lunch but it's $1 reserve if you're super-keen...
I always preferred the Wico sticks on the C64 but my favourite stick of all time was the Gravis Firebird 2:
I lugged one of these to LAN parties all over North America every summer when I was 16~19; probably travelled more than any other piece of hardware I had at the time. Ton of buttons & controls, awesome handgrip, two throttles, DB15 connector, fully programmable via
keyboard pass through, and all the software was installable and ran from pure DOS. Plus it was Gravis, the same company that made my beloved Ultrasound cards. What more could you want?
(Yes, I still have it, in the original box, with manuals and floppies, in storage... somewhere.)
