Back in 2000, the AAT and MTT were new sets. I got the MTT and a Droid Starfighter for Saint Nicolas but somehow I didn't get the AAT in the following years.
This was the time when we relied on catalogues for new LEGO sets, and both the AAT and MTT didn't appear in catalogues I had... (I remember seeing both of them only in one store...)
Anyway, several years later I finally purchased one from Ebay, with the parts in good condition. (One brown 1*4 plate was replaced with two 1*2 plates and one of the droid's torso is a bit loose, but those are the only complaints.)
The small levers with tan base are quite rare parts, as these start from 4$ or so on Bricklink... The instructions are in good condition. You gotta love those screenshots at the top and the alternate model pictures. ;-)
I'll be doing a review of this set on Eurobricks in a while. =)
