I'll second the motion for that 1/72 Ontos in plastic! Matador Models has a 1/76 version that is Resin and OKB Grigorov has a Resin 1/72 available. OKB also offers brass gun tubes while Matador has white metal gun tubes. I have built the Matador and replaced the tracks/running gear from scratch instead of the white metal supplied. The OKB kit seems to have several plastic and resin parts for the running gear. Still on my to do list though.
