Jerry, We have had our Nicolet Vasoguard system for about 6 months and are pleased with it. I have been impressed by their response and implementation of customer feedback. Since we had our machine installed their have been several improved updates. It has all the usual stuff that its competitors have as well as some interesting features/calculations, ie., CW pulsatility index (might be helpful with iliac disease) as well as a number of calculations which have been experimented with in Europe. I honestly dont know if these calculations will add to the Dx but I do like the fact that someone is willing to go beyond our usual but tested bread and butter. We looked at the system about 1.5 years ago (I think) and was not real impressed. Since that time they have hired Rob Daigel as Product Manager. I believe that under his guidance the product has greatly improved and will continue to do so. It deserves a look. You can call me at 1 (800) 992-4676 to discuss specifics.
