Well, I already have a SM2 and am planning on purchasing either a TurboLink or Direct Scan. My question is which are you using and why? The TurboLink is appealing for being Windows based, but I plan on running high10/low 11s and the Direct Scan with 18 frames per second sounds better in that aspect. I know I could have put this in Scan Tool Tech but I know I will get more results here. TIA
