Not saying this is the way to go, but just pointing you to other options:
first of, one thats not been said: For sale section! Often there are one's going on there (know for a fact someone just bought one but is going for hybrid now and will need different TIP. think it was a yellow cupra)
second, I bought one from ebay (unknown company) and have had it on for a good 10 months now. Its one for the Golf Gti/ Audi TT, A3 btw (always more for sale than specified ones for
ibiza's), meaning it has one extra port but you block it off with either a specified part for this which forge sell, or simply a bolt which I did.
Cost me about 60 quid including shipping, however was in better economical times, when Euro was still high (pound as well for that matter) compared to dollar.
good luck
