Has anyone used one of these? Looks pretty good with more features and functionality(200rpm increments vs 500rpm) compared to the current SAFC. Only downside is that they haven't been released in the US and are being imported from Japan so the instructions are in Japanese. There's a ton of them for sale on Ebay, DSMtrader and thepartstrader.. what do you guys think?

Very sexy...

 

Worth it? I don't think I'll need to fine tune down to 200rpm increments.. but it's only $50 or so more than the older SAFC.

 

you can also save 2 different maps as well as you get more ne points that you can work with on the curve..
