It's interesting . . . Italeri 1/35 armor kits are generally maligned but the old Testor's kits were "nice kits" or "great". They are one and the same, except for those kits that Italeri have redesigned or retooled. I love them.
Rob, the Italeri Leopard kits are still considered by leopardclub.ca as being among the best on the market, with disappointing reviews of the newer Meng and Hobby Boss offerings. I just finished their Leopard 1A2 kit and am very satisfied. There are minor detail problems as with any kit, but it built into a very respectable A2.
