orbital polishers

Fellow fiends:

Not a heck alot of brit-car essence in this message but I'm wondering if 
anyone out there uses an orbital polisher on your car.  Any particular brand 
that has the best reputation?  Any warnings/comments on the use of these 
things?  What polishers/cleaners do you use with the thing?  Some friends 
swear by them but I'm worried that if you don't use the thing just so it 
will cause some damage.  

Many thanks, and happy new year!
