Give the kits a chance Excillion, they are great, fun to build and not that fragile if you handle them with care. I built two IMAI kits back in 2000 and they were my first attempt at model building.
I painted them with a brush enamels and the paint is holding great so far and all the joints still work!!!
Obviously they're not toys but I prefer them over the Toynami which is a copy of the IMAI kit. I always go for lineart accuracy, and the Toynami legioss has ridiculously big feet and the canopy is completely wrong.
The Gakken is still my fav Legioss, but that's just my opinon
