^ I had seen those Gefell bars on your site before, John. They look great, but they are very expensive. According to the price list on your site: £149 for the 57cm; £392 for 120mm!!! I suppose that's not all that different than the Grace Spacebar though.
This is not a criticism of you at all, but of manufacturers such as Gefell, Schoeps, DPA, etc. charging for shockmounts, stereo bars, etc. as though they are custom-machined bespoke items.
The 120cm one is so expensive because it is. in fact, *two* 57cm bars plus a joining strip.
Plus made in small quantities and, as with most things, you have to build in a distributor and retailer margin.
They are, in effect, almost a custom made bespoke product because the sales quantity is so small.
All the quality mic. manufactures charge similar prices for these things - and it's only because thay cost this amount to manufacture and sell. If it could be done cheaper and retain the quality, they would do it.
