Duane,
There is a program that many tax preparers are looking at and evaluating. Check out Tax Wise. Call 1-800-755-9473 extension 1148 ask for Jim. The price is very reasonable and their client base has encreased about 10 fold in the last 11 years. They currently have about 75 thousand users presently and he can send you a free CD Rom so you can see it in real time and as far as networking problems that Pro Series folks have had, their system doesn't "Bog Down" due to they way they save their information. Talk to him about that also.
