I'd recommend looking at www.Thomann.de German site but they're cheap and they ship to the UK.
Gotta be worth a shot mate - been eyeing up a trip to 'the street' myself lately.... may be down there myself on Friday, work permitting.
Good luck
Maccy, you've been to PJ's Guitar shop yet (in Portsmouth?)
Quite a selection there with your budget, you can always try and talk down the price e.t.c. too
Can't say I know where that is - Albert Road?
