Which receiver are they using? Stamped steel Hesse or cast aluminium Federal?
If it's the cast aluminium Federal Arms receiver, a complete rifle should cost around $550. If it has the fake suppressor, a little less (bad barrel).
I wouldn't touch the Hesse G3 with a 10-foot pole.
A better alternative is one of the CETME rifles, built by Century Arms, on the cast stainless steel Special Weapons receiver. If you're not familiar with the CETME, it shares the same lineage with the G3 and magazines are some of the few parts that interchange. These cost about $750 and about the only problem I've heard about them is a canted front sight.
