One more.  That's how many.  :)

More seriously, it really does help to have a machine that feels completely like an extension of yourself.  The trick I use when visiting guitar stores is to only consider buying guitars that meet that criteria.  There is a sort of feedback loop involved in the process.  Because you might not know what qualities those are until you've played for a while, and played a lot of guitars.  But once you figure it out, then it really does help your gear purchasing mindset.

Of course, once you do this stuff for a living, then it becomes more necessary to have certain tools for certain jobs even if it's not your favorite extension of yourself.

Keep practicing on the one that works the best for you right now.  But don't let that stop you from trying out all the guitars!
