Little help with value...

Guys, always been a fan of watches and have over the years bought more and more expensive watches. Current two favourites are a nice Tag Carrera and a Rolex GMT 11c.

I have just gotten hold of this...

Quite cheap, not going to say how much as would like others opinions on it.

I know nothing about it but from research I think I have established it's a Tag Heuer 2000 Classic Quartz - what sort of value would you put on it? Fully boxed with all paperwork etc.

Look forward to hearing opinions.

Thanks

Alex
