Troll - Yes, the budget includes the cost of the Vario. Thanks for the reassurance on Silvia!
And what a variety of options you all have given me! Here is the part where I try to apply your logic and try to make an intelligent decision, while taking none of your suggestions

Don't you love it when people on message boards do that?
I think that my best bet may be to go with an SB/DU...probably the Silvia. I'm leaning towards her because of the sheer amount of info out there regarding her, the fact that she has been tried and true countless times, resale value, and her number of very satisfied customers. Besides, I'm already referring to this machine as "her" LOL!
If I am understanding you all correctly, the Silvia will be able to handle one of my drinks fairly well and it's the back to back drinks that would be problematic. I will just make my drink on the weekend first before I make anyone else's and tell them to go pound sand for a bit. This purchase is to make *me* happy, after all!
Sound like a good plan? Thank you all for the time you have spent helping me
