Great looking setup Peter!
With the 12", my biggest problem was always going to be rigidity. The SBS and dovetails are all Losmandy, they are just so solid. I still must be careful if the wind is up, I've just put a sliding roof on my shed and moved in there to get as much protection from the wind as possible (It was always going to be a problem, lots of leverage at this focal length). Your setup may not require the strength I needed and I haven't seen what other suppliers have on offer, I'm sorry I cant be much help with that. I hope the SA supplier is Matthew Lovell, his help in my setup was excellent.
'Local supplier' for astronomy gear where I live is a swear word!
Hope you get what you need.
Regards,
George
