How much does my bike worth?

[vrooom]

I want to upgrade my bike to dh style, but being broke as usual (damn those petrol prices), i wondered how much my bike worth...

My bike spec is:-

Mongoose ritual frame, home painted silver.
Marzocchi Dirt Jam Comp 100 mm fork
single gear setup
Profile 175mm crank
39t bmx sprocket
26" sealed rear wheel with bmx style freewheel with disc brakes
26" front with disc brakes
Shimano disc brakes setup.
Tioga Factory tyres
Avid Disc brake lever FR-5
TH Big Nut headset
Kona DH Aluminum Riser handlebar.
Kona jackst pedals.

I know I may get low money for it but want to know the rough price for it.

here is the pic POOR quality.
