I also have a fetish for Ibanez, get the best model you can for the money - check out E-Bay and ONLY deal with Power Sellers that can guarantee the guitar is setup. If possible it should have a good set of Dimarzio pickups, not the stock Ibz/Dmz's. If you can get a used JS1000 for £450 I would jump on it! Just make sure the frets aren't worn down and that the neck is in good condition - ask all the right questions before bidding, good luck!
