I've just had the pleasure of going shopping for an upgrade to my guitar collection - new bass, new lead, cases, the works.
As a result, I can add a few things to this thread - which I would assume will never go out of fashion, as there are so many musicians and potential instrument buyers on this board.
I discovered something that really ought to be blatantly obvious...
Play as many guitars as you can - good music shops will allow you to try several guitars in one sitting.
To start, see what the shop guys recommend, and remember that they're on commission from certain companies - but also that they do have a clue or two about decent guitars.
Read reviews about the guitars you've tried. Harmony Central is a fantastic place for this.
Return to the shops and try them again, bearing stand-out review comments in mind (e.g. comments that seem to occur in several reviews for that model).
Ask to try similar guitars - by now, you may have a clearer idea of what YOU want from the instrument.
Ask questions - if you can't get the tone you want out of a particular guitar, many shop assistants are delighted to attempt to achieve the tone - and you get the bonus of seeing the amp settings they use.
I did all of these over the last 2 weeks, and ended up with a Sandberg Ken Taylor basic 5-string active bass, and an ESP LTD KH-502. The latter was a complete accident, as a used one had just come in on the day before I was going to buy the Sandberg. I was going to buy a Jackson, although I'd already read nothing but praise for the KH-202s. I played it, and it just felt like my guitar!

I also got a fantastic deal on the price, with strings, straps, cables, cases and even a guitar rack thrown in.
The point is, apart from to show off my new purchases, this method got me the guitars I needed, not the guitars I'd been told about - as well as a very good deal (I saved over £250 on what I would have paid through internet dealers).
