My only caution with AVO would be repair. If somethings up, your probably looking at 3 weeks IF they have good customer service. I'm looking at 2-3 days returned with QA1s.
The Coopers used AVO in their setup:

But they are in England. AVO just doesn't have much of a presence in North America sadly.
