Malthusian23 – you are spoilt for choice there for sure!
With the PX panels you are unlikely to need to send them back for a rebuild. With non-PX it’s just a question of time. The PX solution was a game changer for SL reliability.
They are a pain to ship – so given that I would get the M1 PX – are they 90 or 45 degree?
***Ernestov – could you share further details info pictures for the alternate metal frames please?
Cheers and best wishes
