I agree, damm fine machine and although I don't know who you bought it from, there was a chap I knew named Chris, who I introduced to the machines and I believed he was going to become a distributor.
If it was Chris, please pass on my best to him, as we lost contact and let him know I can be found on my forum Coffeetime, in the UK
Presumably you bought the updated MKII Vivis (a few subtle changes), I did a review on both Vivis and the updated review is on a UK ditributors web site called Bella Barista, you just need to have a search for it.
These machines are quite well known now in the UK, where they have been sold for a long time and more recently have been selling well within the US. Why I like them is the very high quality stainless steel construction, E61 group and great internals. The Vivi for example is about 22Kg+ and much heavier than most comparable domestic prosumer machines.
