Got my 3rd HL today and this one worked straight out of the box!!!!

well,sort of.

Do all the s+s make a loud buzzing noise until the engine sound is turned off?

Anyway a minor detail. This one is the dark green airbrushed metal edition Tiger, (gears, sprockets, front hatches but std suspension and tracks) bought off kissingersommer, Germany.
Well packaged (unlike certain other German sellers) and quick so i'd recommend them, (unlike certain other German sellers).
The paint sort of looks good, from a distance anyway, the fact that it has reacted possibly with the release agent adds to the realism - from a distance, and the cables look good. It also came with a nice canvass roll and a detailed (?) commander figure.
The main thing is it looks ok, works, arrived in one peice thanks to the packaging and was still cheaper (£87 inc post) than the blue base model if i'd bought locally, so well worth it.
And now to the garden battles with the kids.
