I basically only work on 1/72 because I have no room for the bigger stuff at this time. But, I have basically worked on kits from the majority of the makers who are into this scale. Revell makes some really good stuff, as does PST.
PST main problem was their roadwheels, but recently they have started to correct that. Some of the other russian makers are lacking, badly, one example is ACE. ACE has some great ideas, but thier molding is for another forum, UGH !!!. Their decals also seem to be allergic to water, lol. With ACE though, if you put some work into it, alot of work, you will get a nice kit. But for the price, its not worth the heartache, unless your into inflicting self pain. Recommend to those with alot of experience. Im personally going to try them again and see if thier molding is any better, but from I hear/see, it has not.
Roden, SKIF, are pretty good, but you just dont know what to expect from one box to the next. MW, same experience as with all above, except for REVELL.
But,,,BUT!!! Thier is one company from Russia that is starting to be the TRUMPETER of small scale. Thier name is "UM", crisp molding, brass etching, and depending on the kit, rubber tires (thier early 1940 t-34 comes with them !!!) Beautiful kits overall, and they run for $17 to $20. A lil steep for that size, but you get your moneys worth.
The ones I stay away from now because they just seem like toys or not alot of thought was put into them is ITALERI and HASEGAWA. I would build the ACE kits before either of those two.
