I've done a through-hole kit which, though it has a small target audience, works fairly well (it's a HID device using V-USB). But I think it would be more effective if it used the ATMega32u4 with its native USB capability.
Unfortunately, the 32u4 only comes as an SMD part. And if I'm going to use an SMD part, I almost may as well buy cheaper SMD components for everything, cook the boards on a hot plate, and sell assembled/tested devices.
But then it's not a kit, and I like kits. Kits are cool.
So... is there any sense in partially preassembling boards (placing the hard SMD components like the ATMega and the micro-USB port, say) and leaving the rest as through-hole kit components? Would that be the best of both worlds or the worst? Anyone with numbers having offered both types, fully-assembled and partially-assembled?
