In my opinion, there are still enough GTI's around so you don't have to buy one with problems, unless you particularly like it e.g. its very low miles etc. Try to be patient - I know its hard!
You could always nip the photo into a local bodyshop and ask if they can fix it.
As for price, when I bought mine last year, there was hardly any good one's below £750 unless you got lucky on ebay.
