It really depends on how big you want to make them, I'd classify it as this: 1/144 scale = scout class transformer, 1/100 scale = deluxe class, 1/60 scale = voyager class. You get much more of a choice with with 1/144 & 1/100 but the higher you go in scale, the better the quality & design of the gundam, the trade off is the lack of choice plus the price. I still recommened the Strike from Gundam Seed. It's got a modern look, majority of it is white (easier to paint) and the panels are straight forward & easier to work with. Take your time with it though
