Sorry I can’t help but I feel for you Bandit as I too have always used Lodgesons remotes, 7 way for myself, and like you I’ve found them a bit expensive and tried to change to something like the Techmobility remote but failed to get any info on it.
I’ve e-mailed them on my last change over in 2022 and got no response and Motability adaptions price portal and the links within are, to my way of thinking and them being for disabled folk, well there nothing less than a disgrace.
I did think about going to a MB roadshow to see what’s about but the most easiest for me to get to, Exeter, did not happen in 2025 for some reason.
Thankfully for myself I managed to find a suitable car this time around that had an AP including the adaption that’s near on a £1k cheaper than my current car so I was able to stick with the Devil I know because as you know Lodgesons are good but expensive.
Sorry I can’t be anymore helpful.
