I prefer the look of the BV 7 as well. The BV7 32" upgrade is much overdue and some things like the BV4 facelift just pop up without very early discussion that we had as an example for BS5.
So my preference would be this:
Existing BV7 with a large discount. I don't think it is worth to buy used right now, my feeling is that the dealer will give you a good deal since the update is overdue. Depending on how much that is, I would go for the older model. I am more into looks then into picture quality or hdmi connections.
Rank 2 would be a cheap ass Sony LCD to bridge time until BV7 comes if you must have a TV now.
Rank 3 would be BV8 even though I haven't seen it in flesh and may change my mind once I see it.
Rank 4 would be a Loewe. Wouldn't really consider that, I want it to integrate with my BS9000 and BL3/BL2 and whenever I bought other stuff I wasnt happy in the end (Good bye Yamaha Mini System and Good bye Imac which I though would be a good TV replacement until we get some products in the US).
BS9000, BS2300, BC2, BL2500, BL3, Bl2, BS1, BV8, BC4, A8
