I don't have a storefront, just a fellow iPhone unlocker. You can check my personal website out at http://www.begolli.com. You can see the chips and my nice T61 at http://begolli.com/node/3.
I will test them before I send them, for sure. If anyone is interested, I need to get rid of about 14 of them.
Let me know by pm or e-mail (firstname.lastname@example.org)
