I've broken several bolts, and I've never drilled them out or anything. I always find a way to work them out, then I don't have to re-tap the threads.

i think he said it didn't break flush with the block...i assume he means the only part left is inside the block?
i would try loads of penetrating oil (liquid wrench or PB blaster, don't bother using WD40 in place of these). if you have any access to it at all, try to cut a slot in the end to use a flat bladed screwdriver to back it out. if that doesn't work i'd try a left handed drill bit to back it out with the assumption that i might have to helicoil it. in which case you'd need a right angle drill to drill it out, tap and insert the helicoils. i have helicoiled timing belt bolts before. it's annoying, but possible. i rented a right angle drill the one time i had to do it in the car.
i've heard and know of instances where people have JB welded or locktighted bolts in place, so i'd be suspicious of that if it's really hard to get out.
if it's a bolt that screws into the head another horrible option i hate to mention is replacing that head. but might be easier than taking it to a shop if you can't get it out.

The tensioner pully does not bolt directly to the block. It threads into a cast aluminum bracket that is bolted to the block. Pulling the bracket off the block will make removing the broken bolt alot easier or you can just replace with junkyard parts since you need a crank pully, timing belt covers, ect. Good Luck.
