try wirral music on mill lane wallasey! really cheap and great stock
I'd really like to agree with you because I want a decent music shop nearby, but I think the opposite is true. I've found it full of mainly used cheap starter instruments and everything optimistically overpriced. A bit like cash converters but with more musical stock.
Ebay is the place for this. Set your search everything in the musical catagory > for auction only > nearest first > collection only & no post and then wait. Some thing will come up, sooner rather than later.
