I also bought my Tiger from the same seller: he also put a 2000 mAh Ni-Mh battery (rather than the original 1700 mAh Ni-Cd one) and a pre-painted barrel extension (not mounted for shipping size reasons I think, but it was there into the accessories bag).
The package was very very accurate (I also bought a Pershing from another ebay seller, and it was not packed so carefully: some plastic deatils came broken).
And altough not historically accurate (green camo is more for a late tiger than for an early production one), I love the painting job on mine. The basic grey plastic tiger is too much "toylike" in appearance.

The front metal hatches come handy when planning to move the main switch from the bottom to a more confortable location, and/or adding a plug for on-board recharge of the battery pack.

Just a suggestion: check alignment of running wheels, since a misalignment of even 3-4 mm will cause damage to your tracks when running outside. I broke 3 track section before realizing it, and now I have aligned both sprockets.
