I really have no idea where to look for a Wii Chip in the UK, as I'm useless :)
I do know I want a solderless (clip on) chip, and have found the D2PRO which seems to get good reviews. The cheapest I can find it (pre soldered to a clip) is £49.95http://wii-repairs.com/osc/product_info.php?cPath=22&products_id=56
Any better offers/chips? Thanks in advance.
