I'm always looking at alternatives so while browsing I found details of ETS headless bridges - Made in Germany, they're used by quite a lot of high end builders and they make some nice looking parts. Price for the headless bridge is significantly less than similar bridges (ABM) - around £160.
I went to the website but there's no way of contacting them. Apparently it's one fella working on his own and there is a 6 month turnaround.
I did find one of the company's customers who can place an order and I'm waiting for them to come back to me with a quote.
I'll keep everyone apprised on developments.
