Hi

For a start, you may want to verify what each house says they can do versus
what they actually have done on a volume basis. Unfortunately there is no
other way than to look at a number of boards under a microscope, or, if you
can afford it to place a proto order. Sales people have been known to sell
stuff they do not really have to sell.

good luck
