I honestly think it would make much sense to save up for a BV7 40 MK3, that seems to be somewhat future proof.
If you don't care about connecting Apple TVs, Playstations, XBoxes, Bluerays and other HD friends the BV5 might be a good choice. I certainly adore the design of it, one of the few later "classics" in my opinion.
