I have no experience with Viva at all. So, not necessarily a comment on them specifically. I have however sold and serviced audio gear for nearly 40 years, and see this as a big warning sign.
I personally would not support a product from a company that would refuse upgrades or service to second hand owners. I have seen this many times from some very big names. A company that will not support its products is a problem. This should be a factor in your buying decision.
