I think you'd be happy at UBI. I took their 2 week professional course a couple years ago. Newfsmith on this board took their one week women only course. Margot from Luna Cycles, who posts on this board, taught there. Their material and teaching method is sound, lectures and demonstrations followed by hand-on practice of each skill on a variety of bikes and components. You always work with a partner (different person each day) so you'll have help through the skill practices - a real plus if you're a novice at bike work.
