Metal gear legs are the biggest con in modelling. Unless they address detail issues, there's no need for them.
SAC are shit, plain and simple, and G-Factor, who used to be good, are now turning out total dogs (rough castings etc)
Looking great!!
If you use electronic Demo labeller, wipe the fronts of the units with a little ethanol before you stick them on, or they'll start to peel at the edges.
