I'm a lefty and when I first picked up a guitar (age 15) it was recommended that I play right handed as it would give me an advantage on the fretting hand. I simply found it too confusing and uncomfortable. In the end I gave up playing and stuck the guitar in the closet and eventually sold it.

Once I got a bit older and started making my own money I still had a love of guitar so I saved and bought a lefty axe. Easily 1,000 times easier to learn on.

Reality is that yes guitars are more expensive in lefty form and harder to find. Good news is that most manufacturers, Gibson, Fender, Jackson, Dean, make lefties and most stores will special order you the axe you want from the manufacturer.

In the end, my comfort and enjoyment while learning/playing meant more than spending extra cash.

P.S. Take pride in the fact that you join someone like Jimi Hendrix as a lefty. He simply played a righty upside down ;)
