I'd love to see folks selling sync ISDN connections. Perhaps part of the problem is that it isn't readily apparent to folks that the difference isn't just between "115k" and "128k", which at first glance seems to be a 13k (~1K/s) difference. With async requiring 10 bits and sync requiring 8 bits, it is more like a 4K/s difference, and the difference between 10K/s and 14K/s is appreciable. At that point, considering the cost of the communications equipment itself is about $300, arguing an additional $200 for a sync serial card to gain roughly 40% more (66% more cost for 40% return) bandwidth would not be totally out of line. Arguing an additional $440 - the lowest currently priced ET card, discounted, I could find - would be unreasonable, since it would be adding 146% more cost for a 40% return... at that point, it's easier to buy a second TA and ISDN circuit for 230k bandwidth. Other issues potentially include authentication questions (which are easy to deal with via 'login')... people don't like change. :-) ...
