Tanks are about seventeen dollars a blister so you would be pretty much paying for the tanks and getting the infantry for free so dollar wise is a good deal
As a whole the army would make a pretty good late war Grenadier force with a couple more items or you could easily make a Heavy tank army .... They could also be used to throw together a mid war force
So not a bad deal if .... as Laz says you dont want to assemble anything, and this is the army you want to play.

Germans are a fairly forgiving first army
