Is this a good deal?

I have a line on a 08 Transition Dirtbag (large) that a guy is selling but I am not sure if it is worth it or not. New to the game so I have no idea what anything is worth. I looked up Transition bikes and they seemed like an ok company.

Wheels: Mavic XM 321 (xt rear hub, Marz 20 mm front) used but true and strong and pretty light.

Brakes: Front - Avid Juicy 7 w/ 8 in rotor. Rear - 8 in Hayes.
The avid either needs a bleed or has a pin hole in the line b/c it loses power every once in a while.

Front Der: Shimano something or other. It works.
Rear Der: Sram X-9. It has some play in it but it shifts fine.

Head set: 1 and 1/8 FSA Pig with reducer cups pressed in. I can have these pressed out if you're running a 1.5 steerer.

Bars: 30.5mm Kona (cheap but they work).
And a Raceface evolve xc crank set

Prices: Frame and rear shock only = $800. All of the above: $950.

He also has a nearly new Canfield Lucky, size large, anodized grey with blue links with a Fox DHX 5.0 coil for $1,000.

Any advice would be good.
