I've got all the T-72 variants by DML. The kit is generally panned by the experts, but when assembled, it looks like a T-72 to me. This kit is actually a T-72M, the "G" designation is a ficticious identifier for an East German T-72.
Just my opinion, but for the cost of AM tracks, you could buy the superior Tamiya T-72.
Here are some of the AM that was made for this kit:
Airwaves #35009 T-72M1 PE set
Eduard #35001 T-72M PE set
Commanders #5-002 T-72 PE Gill Armor set
Eduard #35329 T-72M2 w/ERA PE set
Armo #35735 T-72 aluminum barrel
Eduard #34002 T-72M aluminum barrel
Kirin #28521 T-90 resin conversion (updated T-72)
Modelkasten K-12 T-62/T-72/T-55M tracks
Probably some more items I've missed.
