I've got one of the purple santamarias on hold, I'll be getting it sometime in the next few weeks so I'll definately leave my two cents as soon as I've had a couple sessions with it. I really like the stats on it though, it should be smooth...
Would like to hear opinions about this one as well, but I trust in it, his others are well received. And if even only 10% of the artists out there really like your machines then that's not too bad at all, we're a picky bunch and have unique preferences. I just got a Kubin cranker(solid and smooth machine for sure) thought no way will I modify this machine, 15 minutes later I'm adding a stay-up spring and a needlebar tensioner and swapping orings...
