There are some changes coming up, however. I've seen talk about the price per point going down.

Best bet is to call DVC and ask. The only places you can get MB is on purchase at VWL, VB and HH. The programs are different at each. I've also seen a thread here that says the price per point is going to $75 on April 15th.
