If you're in no rush then I'd sit and wait out for a bargain to turn up. I got a full length westy rack off ebay for a bargain price. Patience will save you money in the long run.
hiya dont know if it helps i bought both my roof racks new from a guy at Stanford hall (think i paid about £300 for both )
in bare metal just sprayed them silver and treated the wood, went back and got the ladder off him then next year as well,
