I fear you confused prices for compiler built with BEG with BEG itself
(Could you give an URL?). An early research version of BEG, generating
Modula-2, was available in binary form free of charge. It's more than
ten years old now. Since then we have developed BEG into a commercial
product, generating C, with many more features. Pricing depends on
options, desired optimization modules, amount of training and other
services, and pricing model (runtime royalties vs. flat fee); which
can add up to more than 25k.
Your emails apparently got eaten by our overeager spamfilter.
My sincere apologies.

iBurg is a free implementation of code selectors very similar to BEGs
see . BEG, however, generates complete back ends including local
and/or global register allocation, instruction scheduling, DAG
matching for SSA, and other optimizations etc.
iBurg is good at what it's doing. You, however, have to do
register allocation and other back end / optimization stuff yourself.
