My understanding is that BM has no more of these to sell. They sold a few of them directly, but the majority went through retail dealers. BM has very strong committment to supporting their retail dealers. While I am aware of a few 43DMs that went to mail order and .com dealers, the majority went to retail dealers. BM limited the number that each dealer could get. So, if you're stuck wanting one right now, it's gonna be tough. Most of not all are already spoken for. Sorry.
The best thing you can do is get to know your local BM retailer. And yes, this does mean buying your BM42 from your local retailer for $150 instead of from some .com for $125.
