I Googled on "cyclo +polisher" and found, among other sites, another forum with a thread on the Cyclo. People were comparing them to the PC or rotary for effectiveness (Cyclos "take forever" to remove scratches so I use a rotary), for durability (Buy a PC from Meguiars for $200 and you'll get a lifetime warranty - I've gotten 3 PCs free over the past few years), etc.
Although one man's Cyclo took forever to remove scratches, he was very pleased with its polishing capability, and always finished with his Cycle after using the rotary.
When questioned why he'd had 3 replacement PCs in so short a time, he answered that he wears the cords out, so rather than replacing them, he sends the whole machine back to Meguiar's. They ask no questions, and send him a new one.
Cyclo owners say they've had their machines for 8 or 9 years with no trouble. One guy who owns a Cyclo and a PC says he prefers the PC when shampooing carpets because he has better control.
That's all the extra-DC research I've done so far...
