I don't know what they are charging for them, but a Google search  
shows that Ohmite still makes and sells Victoreen Hi-Meg resistors:

An inventory search on the part number RX-1M1009 shows that Ohmite  
has 167 of the 10% tolerance variety in stock at the factory. Ohmite  
doesn't list a price.

Online Components has two of the 5% tolerance variety in stock at  
$54.84 a piece:
