A few computers, some digiboards, a bocaboard, 12 modems and a T1 to my first apartment in Boulder. Of course the BBS only lasted 18 months and never made any money but it provided an early (1995) and very in-depth window into what running an ISP would be like and eventually a PaaS/IaaS (or whatever rsync.net is). In second place for "best money you have spent on professional development?" would be hotel/flight costs for Defcon 6-10.
