I think the spinlite system is pretty good. There is one near by where I live and its been there for 2-3 years now. Cleans really well and the owners keep the machine in good shape and its setup correctly. I guess the ones that ditch the system might of not known what they were getting into before buying it. It does look like it needs more attention to keep running then a sonny's system for example. Running those brushes at higher rpms might cause damage due to there design. Spinlite and sonny's are my two favorite machines.
