Ah, the good ole Panzer 4! I started doing one of those back in 1969. I still have it built up kept in special place. It's only missing a few small parts, the CO hatch and so on. Right now Im finishing a DML Pzkpfw 4 ausf F that has Gunze Sanyo heritage. Those are long OP now, but I still have few in the stash. I have a soft heart for the Mark 4. It was my fav Roco pre built model as a kid in 1950s. At the time they a models with both short guns and long guns, and skirts or not. I was a little confused by that. That was long before all the books that explained that. My friends and older people were no help. I've lost count of all the kits I've done of Pz 4, Italeri, Dragon, Gunze Sanyo, Tamiya, old and new, and Tri-Star.
The Monogram kit realy got me into tank models. There was only a couple of Revell and some Renwal and a few 1/48 scale and 1/72 Airfix kits around.
Oh, and the new Border and Rye Feild kits I have only one, a late G. They look very good. So we will see.
As for the various track types, I have done them all. I have only one that broke ot the Italalei Pz 4 ausf F. It was a clean break that could be fixed, but the kit is close to 35 years old, so why bother? Since I like glueing parts together, the more complicated a kit may be is not an issue with me.
My favorite is the newer Dragon kits. Those with plastic smart tracks are the best. I got lots of those before they got really expensive.
