Check out www.tgajets.com, you just can not beat them for quality and affordability of entry level jets. Df or turbine. The site is not the most informative but a simple call or e-mail will answer any questions that you have. I bother those guys all the time and they are nothing but nice. As far as a first jet goes I went with the byron version F-15 and have never had a problem from building to flying. Give them a try it can't hurt.
