With all due respect to the other posters, Martin and Taylor are not the only answers. If you want heavier bass, Taylor is really not really an option.

Since your Simon and Patrick has the sound you like, maybe you should just change the way you hold it. I've seen some very small people playing dreadnaughts and jumbos comfortably, and playing them well. Sheryl Crows's Gibson J-200 looks almost as big as her.

If you need to buy another guitar, a good balance of great sound and low price is Seagull. A quite a few professional and semi-pro musicians I know play Seagull 6's.

A guitar is for making music, there is nothing more important than the sound. At your stage of playing (I take it you are not a beginner), when shopping for a guitar make sure is is well made and has a solid top rather than laminate. This will ensure that it will improve with age. Try the neck for comfort playability and intonation and above all listen! If you already have an OK guitar then your next one should sound so good to you and feel so good in your hands that you smile every time you see it and never want to put it down. I have two like that so far, a Seagull "A" and a 1964 Gibson j-45, plus 6 more guitars which I don't play anymore. I have a Sigma and and Epiphone, OK starter guitars but Taiwanese made. Well constructed, but without soul.
