I try to take time to leave positive comments on products and services that I am very happy with. Rarely leave negative comments. Left some negative on Andy Sabisch's Equinox book. Thought it had too much fluff to pad the page counts. I am ordering his book on the CTX3030 because I have heard a lot of positive comments by forum members. I hope it is good, since I am getting a CTX3030 in 2-3 weeks.
