Another idea.....would using a walker at the steps solve the problem?? Several of our assortment of doctors have a walker set up at the scale to help patients step up and down. Personally, I try to avoid the scale, but always get caught, rats! That would certainly be cost effective, lightweight, portable. If the ramp idea works better, maybe contact a small metal fabricating company....one that needs the business, and they may be able to fix up something rather than going with the medical supply companies that tend to be way too proud of their products....especially if insurance is paying for it. I think this is doable. Good luck.
