old thread, but I am now in the same boat, looking to add a bunch of Besta's to my office (especially since they are 15% off this month). depending on which glass I go with (Vassbo or Glassvik) the cost will be $1800-$2500, crazy how expensive glassvik is but I have a couple in my movie room and they are awesome doors.
I went with 2 B/B bestas for my movie room, they flank my sub and center speaker, super dark room which is why I went black, one is still empty and the other one has Sideshow statues of Maleficent and the Evil Queen in it, each with a ikea spot light LED on them, I love the look, they wouldn't look right in a white cabinet, the dark with spot light gives them that evil look they are supposed to have.
BUT my main figure room will be my office, which has cherry wood floors, white baseboards and will have light gray walls. I am planning on 1-2 lights per cabinet but wasn't planning on the mirror add on for all of them (maybe a row or two).
Wife doesn't want white, but I kind of like that Museum look, but then look at the two I have in my movie room and love how they look in B/B. can't go back once I make a decision as I am ordering a lot of them.
One of my fears is the quality over time though. It is one of the more expensive Ikea items when you go with the glassvik doors but the cabinet is still MDF, super light and cheap. although I think for customer wood cabinets I would be looking at $10K, which I would rather spend on more figures
sorry about poor quality on the picture, phone pick
