I purchased a set of CNC'd Isaac (Mendel derivative reprap/repstrap) from Brett and Todd this last week, off their website. The price was very reasonable, the communication was excellent (I had lots of questions), and the delivery was swift.
When I received my kit, the parts were separated by assemblies in labelled paper envelopes. The finish of the parts was surprisingly clean, and I am well satisfied with their work. I would recommend them to anyone. I'm getting their first thicksheet kit as well, with an acrylic bed. Check them out, good to work with.
