"Bought a like-new Inside Ride rollers unit from a friend and used it just a couple of times. Rollers sell new for $850; willing to sell for $700 obo. Unit comes with allen wrench, hex wrench and instructions. If located close to Bethesda, I will deliver to you. See http://www.insideride.com for more info and videos. I can e-mail photos of my unit."
Please e-mail me at mail@sidelfamily-dot-com if you are interested, and I'll put you in touch with the seller.
