They're from HaiPham at "Precision Tamper Maker" (available through e-bay). I'm very pleased with the quality of his work - as well as the speed with which he fills orders. He makes quite a few different models (seems he's been expanding his line with new models all year) and each model is highly customizeable as to base diameter and choice of convex or flat bottom. The difference between the two I have is that the first has a stainless steel base and an aluminum handle. The second is all stainless steel and much heavier - a full pound. The second is a newer design. I love the extra heft - and may eventually replace the older aluminum/stainless steel model with a second all stainless steel...
BTW, both tampers actually look much nicer in person than what appear to be the "CAD" and "semi-CAD" images he posts and I've uploaded. (At some point I'll take/upload actual photos of mine, but presently, I'm at work with one tamper at home and the other at the beach house...)
