Nic, I've put together a "premium" reflector from custom work - optics done by Mark Suchting (Deep Sky Optics in Berowra, username "lambda20" on this forum) and tube made by Gary Mitchell in Condell Park, Sydney.
I bought a Losmandy G-11 to carry it, very happy with the results. There are some images on my website:

Mirror cost around $1300, Tube cost around $300.
All up, with mount, goto and accessories it was probably around $10k.
