How much are my 172 alloys worth?

[Bucko]

Sorry no pics available but how much do you think my 172 alloys are worth? They could do with a refurb after 8 years worth of light curbing but nothing serious.

I'm only asking as i'm considering joing the flock with Turinis but i have a very limited budget...

Scrap that, £150-200 isn't anywhere near enough to fund some Turinis in my current financial state
