As an ex Shorty Plus owner, I'd say be wary of these barlows. I might have ended up with a bad sample but I did not like mine. Also be wary of reviews on excelsis. I never used a GS basic 1.25" barlow but I get the impression that you are getting what you pay for with that one. Since the UO 2" barlow is discontinued I don't know what else to recommend around that price. GS 2" ED barlow maybe...
