I read build logs and try to stay away from problem kits.I don't mind complex kits if they are well engineered,most Dragon kits I have done have been good,Tigers,Panthers,Stugs,III's are good,Meng are complex also but build up well.Tamiya are simpler and excellent.
I don't mind inexpensive well done kits either as long as they aren't junk.
I don't want to slog thru an ill concieved,over engineered,bad fitting kit,wasting my limited hobby time.
