For testing the big stuff (and perhaps for everything), ARRL commissions 
members to buy the rig or whatever from a regular ham radio retailer 
with no indication that it's for testing by ARRL. That way there's no 
possibility for the manufacturer to supply a specially tweaked one or 
one that's had more than the usual amount of Quality Control testing.

You'll then see ARRL auctioning these items off from time to time -- 
announced in QST.
