Not agreeing that the OP needs a module, but this is one of the best companies rebuilding them; BBA, Taunton MA, 866-573-2740 toll free. Never had a bad job from them.
My personal opinion; get a second opinion if you have not been using this garage long enough to have an established relationship. (If you pop the ABS motor fuse you'll light up your dashboard. Fuses sometimes fail on a one shot basis due to the ABS pump not having operated in a long time. Don't want to second guess the garage, they had the job in the shop and may be correct in the diagnosis.)
