This is why you should try out the axes that you are looking at before buying. Most people like the Pacifica, but obviously Maiden didn't get on with it. You're a lot more likely to pick up the guitar and play with it if it's one that you really enjoy playing. You could buy a £2000 PRS, but if you don't get on with it you're less likely to pick it up.
I'd visit as many shops as possible and play as many guitars as possible so that you get a feel for what you like. It wont take long before you start to firm up ideas.
