Jon,
good timing, if you had done it 4 weeks earlier this would not have been the case. He was making 50 I believe 8x20 film holders for some one over seas and I had to wait for him to finish that first so he could make my stabilizer, which means I would think he made more than one set and had it finished by the time you ordered. I have installed my wind stabilizer and the following is my assessment.
1) all parts are of top quality
2) had no problem installing the permanent parts.
3) at max extension my 8x20 is very rigid, making the stabilizer worth getting.
4) every one says it take forever to put together. It does take about 5 mins to put on the camera, but if you are using a ULF cameras, don't think you are going to get a fast shot. Plus if you are going to continue to shot, then just take off the bar and leave the rest till you are done.
Alan makes a great product but I didn't like the fact that Fred Newman had to say he was sorry several time because of the wait. NOT GOOD BUSINESS!!
