Hi, Dan,
Try D.J. Ellis Ltd. (Nuneaton, UK) Tel: +44 24 7635 2888
Dave has had some pillars made recently (with outriggers) and I have a
set for my Yella Terra roller rockers. I can't say what they will cost, as he's
my friend and did me a cost-price deal, but it will definitely be less than
$400!
(I also have connections with J.E Engineering, and I know they were upset
because
he got them made so cheaply...)
Good luck with the project!
Regards,
Franc.
