I needed two of these, and a batch 10 on ebay cost less than 2, so I've got quite a few left over. Anyone who needs one of these is welcome to one. Five bucks to cover the shipping and a paded envelope would be appreciated, but isn't necessary.

It should work with anything with a MIO slot. The first list I came accross had these pinters:
