I can now relate. I ordered a RockMite and Tuna Tin 2 from Rex (QRPMe) recently. No acknowledgement of my order after several days, so I emailed. He replied that he'll get to it in a few days and that he has "other chores" to do.
One of the kits arrived missing a 20m crystal. I emailed him to request he send me one, as he asks buyers to do in the instructions. That was a week ago - no word (or crystal) from him yet.
I'm sorry to have ordered from him. Lesson learned.
