Janice-I can't imagine any circumstances in which the PCBM shell would be attractive to a RM candidate. Clean pinks can be had for around $100 thousand plus a five per cent equity share; fully reporting BB shells run about $300 thousand with the same or slightly more generous (to the seller) equity terms.
Of course over in PCBM land the sheep still consider themselves to be an asset in a RM, not a liability to be disposed of in a massive RS.
