Tried them about 4 years ago (They were obsolete that long ago) and they wanted to sell me a minimum of 1000 of each which was ridiculous !!
However, I happened to be "Shipped" over to our sister plant in Singapore for a couple of months in 2007 and one of the Engineers put me on to a local, small electronics shop who got, and sold me 50 of each size. They were Philips (OEM), still in their bags.
Lucas, the manufacturer of the Becm, no longer manufacture new units as their stock of components is depleted. As far as I know, they only recondition returned units...if they don't have the components in stock, they just bin the faulty board(s) and it's one less Becm on the planet.
