Bill,
I have the KV-2 (same tank different turret) and it is a beast, nothing stops it. Driving it is a little twitchy and even though my T-34 (also Imex/Taigen) is a bit more civil, I prefer driving the KV. It should keep you happy until you get the modification bug. I already put a Clark board in mine and now modifying the upper hull for an SU-152 conversion. You won't be disappointed.
