As much as I do not like ebay or CL lately, you might want to get a high quality used one for a deep discount. I would try not to go beyond a 2006/7 model for no other reason besides the fact that it will have had more time to be abused.
The main thing you need to worry about is the length of the steer tube vs the length of your head tube on frame, your HS stack height, and the stem height.
good luck and welcome!
