I brought a Hori Arcade stick from Plisken from these forums (I think he has some left). It has 8 buttons and auto fire. Very nicely built as well, not as heavy as my namco PS one, but the control/buttons are perfect. The stick is quite clicky which might not be to your taste, but I like it a lot.
Not used the Hori stick, but I can vouch for the quality of the official Sega one. It's well built. Not quite up to the DC one in terms of the actual control, but it's not bad.
