I wouldn't call myself a "freak." We who follow the True Faith tend to call ourselves "Shermaholics."
Now, if you promise to show the proper respect, I'll tell you a bit about the kits you are asking about, Jeff
The Tamiya M4A3E2 Jumbo kit is not what it claims to be. It includes parts to make the hull thicker, plus a new turret, but the final drive is from the original M4A3 kit and is not bulky enough for a Jumbo. Also, there are many, many questions about the shape of the turret. It seems it was made from some bad drawings and bears little resemblance to the real thing.
DML 6041 is the Coldstream Guards Sherman V (M4A4) with 60 lb. Typhoon rockets. Not bad, but it suffers the same problems as all DML M4A4 kits: the rear end needs to be fixed (a bit a surgery) and the bogies should really be the horizontal return roller arms, not the upswept.
DML 9009 is the Korean War M4A3E8. This kit started out marginal and got better. Early issues had lots of problems, but DML fixed most of them in subsequent reissues. I have an early issue and a late issue. The early kit's biggest problem is that its mantlet is upside-down. This was fixed in later issues. Also, the early hull had problems, kit 9009x included a corrected resin hull, and later kits have the corrected hull in plastic. Not bad, needs some tweaks, the suspension is a little fragile, but builds up nice.
Italeri kits (sorry, but I don't want to dig for numbers -- check the kit list on the AMPS site to find kit numbers and mini-reviews):
M4A1 -- decent out of the box...the only major problem is the gun barrel, which must be replaced with an aftermarket part because the kit's two-piece, stepped barrel is dead wrong (many people believe this is because the kit was based on a post-WWII Italian Sherman that had its barrel cut off and then spliced back on with a piece of pipe).
M32 TRV -- nice, but depicts a vehicle that never existed. Replace the hull and you're in business.
"Jumbo" kit (sold under various names) -- really an M4A3. Not a bad kit with a bit of work.
New M4A2 -- really an M4A3 with lots of extras. Not enough to build a "true" M4A2, but there is a replacement deck, plus wading stacks and "wooden" side armor.
M4A3 with T-34 Calliope --The M4A3 again, with a Calliope rocket launcher that builds up nice with a little TLC.
M36B1 -- M4A3 hull with a M36 turret. The turret is needs major surgery to make it right and there is no interior if you fix the turret.
M7 Priest and Kangaroo -- I lump these together because ehy are basically the same kit. Both are nice OOTB, but depict very late vehicles and really need to be backdated to depict service vehicles.
Did I miss any?
