Hi v-rap. I completely understand your frustration and am sorry that you had a poor experience with Veritas. I also share many of your concerns and was hoping to quantify it in my analysis. Since you have also taken Veritas, I would love to get your feedback, given you have the time to read it!
Also, the link you posted is broken. I believe it refers to this thread: http://www.www.urch.com/forums/gmat/33008-manhattan-vs-veritas.html
