You could probably find tool kits cheaper
here rather than the site you listed. Check the other categories for proprietary tools and such. Some sort of mechanic's stand will probably be really helpful too, after tuning up my bikes flipped upside-down on the handlebars and seat, I'm finally ordering a real stand.
www.gvhbikes.com offers fairly decent prices on build kits, if you have a bare frame you want to build up, although that may be out of your price range. Never bought from them myself, but I've read reccomendations from others on this forum.
