Alleyoop who sometimes posts has a FS Ibex. I think they are solid bikes but I don't know much about them. I would get the best component group for your budget, your riding doesn't sound like you are going to be thrashing the frame or anything.
I learned on a Scott HT I found on Craigslist for $200. She has a decent gruppo and is about at $700 bike new. You don't need to drop $2k to have fun and learn.
