Yeah can't fault AmigaKit up to now. So far I have bought a funky USB Boing Ball Mouse, a year's subscription to Amiga Future. And just recently I bought an AmigaOne keyboard and Sam 460ex.. which in fact arrives tomorrow!!
I'd buy promotional merchandise as well if they stocked it... a Mug, a Pen, a Keyring... a mouse matt anything like that would be cool too.
