Yammieplaya,
My only acoustic guitar at the moment is a Yamaha L-25A that I bought used in about 1984/5.
It sounds great and has always had an incredibly low action. Sometimes I'd like something with a smaller body but, given how long I've owned it (and how many dings I've put in it!), I couldn't get rid of my L-25A.
It was made in Taiwan and as with your L-15A, there doesn't seem to be a huge amount of information out there about them. I'm not sure what the differences are between the models but here are a few photos of mine:
