<html> <blockquote type=cite class=cite cite> What to buy depends on what you want to use it for. If you just want a little box that tells you what to do then I suppose the SAT has the best track record for overall performance. </blockquote> Hi Ric,                You are behind the times, Pocket RCT, the lap top is gone, the iPac is supper convenient   and very  user friendly. Instant turn on.  Used with Spurlock's jig it will never scratch a plate. A friend of mine and I did some side by sides with the sat3 in the high treble, we both agree, no contest.  The fact that the i PAC and jig can be placed on a high treble tuning pin, allows it to really get a reading on the top notes, of verticals. AS for the tuning, not a Hill of beans difference.  Both are great machines. But the i PAC/ RCT is a lot less money. We both agreed that sampling, to calculate a tuning was a little faster with the RCT Pocket.  First with sampled with our own machines then we switched. Display was the major difference for both of us.  I like RCT's spinner, he likes the lights. It's what you get used to I guess. regards Roger. PS Yes I will bring it. <blockquote type=cite class=cite cite>RCT will do as good a job and offers lots of other goodies, but you have to have a portable PC and deal with limited batterys. Upgrades in either case are not included in the origional price.</blockquote> </html>
