I have an Easton but it runs anywhere from $65-$95 from what I've seen and I use it as an infielder's glove. It also hase a gel pad built in near the palm so you barely even feel the ball hit the glove, and it breaks in very easily:
I'd recommend just going out to Sports Authority or Modells and seeing what they have, usually they have some reasonable ones that'll work well, and it'll be easier to find a lefty glove in person most likely. I've seen some gloves that are like pre-broken in (Wilson or Mizuno maybe, can't remember), for low prices which are also a good buy.
I also have a different Easton glove, an outfielding one that I don't really use but it's for righties... otherwise it's barely used and in good shape.
