I wish I had Goktimus's restraint - for me, it's a case of "see sticker, place sticker". Mostly anyway.

Here's a couple of sets I bought recently:

TR Doublecross Twinferno



I was initially unsure about the wing "scales" - I really liked the smoky clear plastic of the wings. But they really look good.
Also loved the small touch of the "sparks" on the dragon chest, near the fake "wheel", a clever homage.

Then there is TR Getaway Breakaway



Some neat additions in vehicle mode, and to the robot legs.
