I have searched the forum and found a number of threads on this topic, but they seem to be old and out of date.
I've had my Summit for a few years now and due to space and time, just managed to dig it out of storage and start playing again!

I've never been a fan of the stock driveshafts - I can't stand the little grub screw, it always manages to loosen! So I'm looking for recommendations for an upgrade. I like the look of the LEM in the other threads, but can't find a supplier and I think the website is down, or they are no longer manufactured.
These look good though ProLine PL6274-00

I'm from the UK so a distributor who delivers here would be preferred.
