I am informed (in another post) that Lik-Sang have got a stock of Origa 1.2. if they have the US version, get that for closest fit to Messiah functionality. I'm very pleased with the OrigaChip.

Otherwise, get NEO2.2 while stocks last - it's just that you've got to deal with swap methods and specific GS2 versions, etc.

In this sad litigious age, any advice of mine that you follow is at your own risk, of course.
