ANOTHER PRICE DROP!! S.A.M. “The Original Spinal Analysis Machine”, old-school with pneumatic pump to let the person you're screening see what it feels like if you "level them out" (e.g. pump up their low side). It's a beast – pretty heavy but built like a tank. Missing the left lower "ruler" to measure pelvic height difference but could use a yardstick. I've sent a message to manufacturer to find out if a replacement is available. These things are still being produced and sell for $3,347 plus tax at Scripphesco. Includes free-standing poster holder and chiropractic posters. Asking only $90. Prefer local pick-up. Can ship but you figure out the shipping costs from my zip including palletizing, etc, pay shipping and again, very heavy with all the parts.
