Robin, I've used them a couple of times, great service & del.
BUT, waiting this long with the same reply each time, needs an assertive email from you, to find out what's going on.
I know that Peter Read (SDM) has dealings with them. One of the principles (I think it was a 2 man operation) was killed in a motorbike accident last year and that has caused some issues, but Peter told me that as far as he knew, they were back on track.
Good to hear. I have been very happy with the quality of the items supplied. The holder I bought has made collimation much easier on the 20" and the pivot system and powered ground board kit work exactly as advertised.
