Wanted pcs and sets

[Graham]

In addition to all the selling and trading, i am looking for particular pcs and sets (which should give some guidance for possible trading).

- 9v & 4.5v motors and wires
- yellow, blue and white technic beams/liftarms
- #8421 crane
- sets with power functions, esp the bulldozer

At the moment, that's all i can think of. I'll updated changes later.

Thanx
