I did get one of those GM Tech-2 clones. Got it here with a plastic case.

It looks nice with no visible defects except for the main 'Tech 2" label on top which is slightly too large for the recess where it is stuck. Only had it a day now and after using it for a coupe of hours, the "Oh-no I bought a DOA lemon with no way to return it !" devil hasn't appeared yet. It seems to do everything as advertised, as much as I can tell for now. All the Bi-directional actuators work fine. The graphs and tables of PID's look good. Can read the ABS, SIR, and body modules ok. It came with a 2013 data set already installed, and while I may have to order updates from China from now on, that's ok with me. I may ever need them.
It's larger than I thought, almost takes two hands to carry. The OBD cable is huge, presumably meant for heavy shop usage. The firmware covers the 1991-2013 years, including Saturns. The case is the size of a small/medium size suitcase. There are 5 adapters and 3 power cables (AC, cigar lighter, and battery clips).
