I'm used to finding that prices for goods for the disabled can cost as much as the firm can get, but I expected better from HSL.
Th controller for the chair I bought met with an accident caused by me and it costs £75 ex VAT for a replacement.
Have you thought about looking on ebay for a replacement? I will be surprised if there is not one available. People sell them once they or their relatives no longer need them.
I've tried looking for a S/H controller but no go.
In reply to woofgang, yes they are in business to make money but many are notorious for ripping off the disabled. A couple of years ago it was reported that the owner of Acorn stairlifts, (who invented the excellent device in his garage), took an £18m dividend. He lives in Monaco.
