I think it's the best vehicles in 2005... either that or the ARC-170.
I think that pretty much all of the vehicles this year in the 20 and up range have been stellar and well worth the money. I've become a huge fan of the ROTS Jedi Starfighters, and the Droid Tri-Fighter was a favorite from the moment I got it. The TIE has the coolness factor going for it, as well as the accuracy factor, and aside from a few minor points (the POTF2 pack-in which didn't bother me that much honestly, and the inflated price), I think it continues the trend of great vehicles this year.
A question for everyone though: I know I mentioned earlier in this thread that one of the cannons on my TIE was partially unpainted (one is silver with a red tip and the other just has the red tip on the unpainted blue plastic) and I wondered if it was a factory error on mine. The other day, I was looking at the photos accompanying the GH review (presumably of Mike Sullenger's TIE) and his had this same "flaw." Does everyone else's TIE have this same problem, and if so, is it really a flaw in the toy and not an accuracy that I just never noticed on the film props themselves?
