I'm with Roseysue - LOVE having no dog-ears to trim with triangles! Plus not having to cut triangles and have them be just a bit off - now they are perfect every time!
Strip cutters - there are tutes out there (youtube has lots) that will show you how to mark your strip dies so that after the strips are cut, you carefully lay them on the die at an angle and get either diamonds or parallelograms.
Also, there's been lots of discussion lately re: Sizzix - they are less expensive, but were orginally meant for scrapbookers. Don't think they have strip dies available, but there is info available on using dies other than theirs in the cutter. You might want to check into those.
My personal choice was to get one that was specifically geared to quilters. Like the Studio, but no room for it - let alone the extra expense. So I got the Go! and love it.
