You're welcome, glad to help!
While I don't doubt the VR10 being quite capable, like I mentioned, I own one and I'm quite pleased with it's performance based on it's size. Nevertheless, I can't see it keeping up with the VRC at higher volumes or in a larger setting.
The VR12 is a large center, so if size is an issue for you, you may need to keep the VR10 or look for a VR920, which is a step up from the VR10 and is larger width-wise, but has a lower profile compared to the VR12. There's a slight performance trade-off w/the VR920 as opposed to the VR12, but it's a solid center, too.
I believe BA stopped production of the VR series or has limited it drastically due to their newer product releases. I'm not terribly pleased with their focus on their Horizon series which is focused more on home decor integration. Their new E series speakers are impressive which I believe is a combination of their VR and VR-M lines with new styling, though they're quite expensive.
BestBuy Magnolia used to carry the VR line, so if there's one local to you, you may want to check that out. Online, I believe Audio Advisor still carries a few VR models. Other than that, eBay or AudiogoN is your best bet, plus you'll likely find a good deal if they're used but in good condition... -TD
