I am a bit obsessed with my local, pop in every week.
You just never know what you will find!
They do usually try it on by charging too much at first but give it a couple of months and the price steadily drops.
You have to play the waiting game and pounce at the right time before somebody else does.
I bought an ESP LTD D-4 there last week for £210, absolutely mint condition, like new.
But yes, they are awash with crap instruments that make me sad.
