2.5 to 1 gearbox

[racer]

Hi All
Bit of a tricky question to answer this I suppose because they don't come onto the market very often but can anyone give me a ball park figure for a bullit ratio gearbox?
I'm currently restoring a Ginetta G4

I know, I know, boo hiss (I have at least owned an Elan and an Elite) http://www.flickr.com/photos/48083377@N03/8467343811/
but I'm considering selling my spare 2.5 to1 1st helical box to help with restoration costs on the Ginetta.
Any thoughts, figures, would be welcome

I've only seen a couple change hands in the past 2 or three years Steve, and from memory one was ?600 straight from a car ('was working well') to ?1200 with new layshaft and all checked over.

I would be interested at the right price!
