Thanks for replying John I really appreciate it. The info about the regular carafe on the Vitamix being sufficient to grind grains every once in a while helps me to confirm my decision to...drum roll please...exchange my Blendtec for the Vitamix. Here is my update.
So yesterday, I happened to stop in another Costco and lo and behold, a Vitamix demo was going on - oh happy day for me. Again the demo guy was really nice, except for the fact that he kept overlooking my questions to answer the questions of the other lady who happened to be in her exercise attire, which made her look more healthy and more likely to purchase than me

Anyway despite the demo guy ignoring me, I continued to watch for a good 30 minutes as he demonstrated (for the other lady) the Vitamix's skills - it spoke for itself. I need not go into detail as I'm sure you all know how powerful it is; plus the treats he blended up were equally as tasty as the blendtec guy's.
However, what really caught my attention was the ease of use. Being a novice, I really think the Vitamix will be easier for me to operate. Again despite him ignoring me (you can tell that p'd me off), the demo guy was nice enough (after the other lady left) to show me one-on-one how easy it was to operate. During my use of the Blendtec, I discovered that it really isn't just pushing a button and your done - more often than not I had to pulse it a little more. And when I had to blend something that wasn't on a pre-set button, trying to use the speed buttons was a bit of a chore to say the least. It wasn't really that bad, it's just a bit more work than I imagined. With a little more practice and patience on my part, I would probably soon get the hang of it and be on my way to becoming a Blendtec blending pro.
But something else I really like about the Vitamix was being able to use of the tamper to help determine when the smoothie was done. Since I'm so new to blending, I don't have enough experience to be able to tell by sight if something is done, but the demo guy showed me how to use the tamper (i.e., how the smoothy slides off) to gauge when it's ready (instead of having to turn the blendtec off, take off the top, and spooning some out to see if it's done).
And John you're totally right, that 96 oz. jar is way too big for me, especially since I don't make as much as the guys made in their demos - maybe half of what they make, if that. I can definitely use - probably a little better if I had a tamper - but I don't really need it. And in fact, I'm thinking about getting the smaller wet carafe at some point for the Vitamix as I think I would use that more than the larger carafe and/or the dry carafe.
Anyway, none of these things are really big issues that make one blender better than the other in my opinion, they are just preferences that I think will make my blending life easier which will in turn keep me using it daily. The Blendtec makes a wonderful smoothy, but the buttons make it a little harder to get use to for me. But I have to say that I will miss the sleekness of the Blendtec and the way it fit nicely - aesthetically and physically - in my kitchen. I will have to put my Vitamix in a different place, but on the bright side, it's placement will force me to see and more likely use it daily as it's on the counter space I regularly use anyway.
