When choosing a new guitar, I follow this 8 steps methodology:
1. What music/song I want to play? 
     - For illustration, I want to play EC acoustic unplugged songs
     - This will narrow down to type of guitar - Acoustic Guitar
2. What does the artist(s) use?
      - EC uses a Martin 000-28EC (and a lot more .... but use this for illustration)
3. What's my budget?
       - If you have it, buy the Martin else look some more
       - For illustration, budget about S$300-400
4. Based on my budget, what are the acoustic guitars available
        - check out music online store for indication of price range, eg. music123
        - this will narrow down the models of guitars
5. What are the features I desire
        - such as solid top acoustic, dreadnought
         - further narrowed the models
6. What are the reviews of these models?
         - check out website like harmony central
          - based on review and judgement, further narrowed to a few
7.  Where can I find it in Singapore?
        - Call the major stores
        - Try it out and let your feelings guide you
8.  Are you likely to be a GAS victim?
     IF NO, - Buy the guitar with the 'feel' 
     IF YES, - go and buy the Martin. That will stop you searching for a while 
Hope that make life a little easier when you go shopping next.  :wink:
