Yes.
And where they were once easy to get then now not so much.
Everything is becoming locked down.
You will pay hundreds for one. Unless used.
But when you consider that all the REST of the stuff can be aquired over time cheap. Or part of a chair. Then it suddenly looks cheap!
Think about this.
I have 3 complete full house rehab style chairs with all the seating bells and whistles and high end joysticks etc.
Came on my carefully choosen chairs.
In addition!
I have 3 more, identical full R-net systems in a box. As backups/spares/to convert future LOCKED DOWN chairs, to programmable R-Net. Complete brand new joysticks and the rest either new or literally AS new. Full high end systems complete with seating components, and bus cables etc.
I also have a few spare LOWER end joysticks, also new. So another 3 basic ones or the cheaper plastic colour joysticks. All are completely interchangable. And a few spare seating and power modules... So a lot of R-Net stuff. Total cost of ALL of it is around £1200 to build or convert 5 full chairs!
So a few hundred on a dongle equates to a tiny percentage per chair. It means I can properly program all this stuff...
See this?
It is basic! It can replace ANY of the other joysticks as a backup, plug and play.
Its also completely new, and he accepted my £40 offer and added a free bus cable...

EVERYTHING needed here for a full rehab high end chair (£175):

- Full system. With 6 actuators, lights, all loom parts.
CJSM2 joystick £125 new.
120A Power Module + ISM6-L seating module + cables £50
Total, £175... Seriously.
For a full complete rehab powerchair all power functions with the besto ptions available.
I buy when they appear CHEAP and I do so fast! And only NEW or from a NEW CHAIR, or from a FACTORY REFURB supplier.
You seldom see these things at good prices as they are bought up fast by people like me. I watch eBay from half a dozen countries, search for the stupid names that people that dont know what they have call them. Like pride controller, ECU, "Brain for lights" and 100 other things. Those are where you find bargains for around 2 minutes!
