Yes, PCMFlash is very nice to use. Haven't tried their VAG stuff yet, because already have X17 and Kess.
The only "catch" is its just software. You'll need your own J2534 cable. Also, pretty sure it doesn't do TP2.0, just UDS (for MED17).
I already have a J2534, so it's nice not having to pay for extra hardware. It looks like there are two separate MED17 modules, one USD, the other TP2.0. I pulled the trigger on the SIMO module. If that works well, I plan on getting MED17 module as well.
