I have been lucky, I just ask at breweries in my area. I tell them I'm a home brewer and describe what I'm building and I have been able to score 2 kegs free. If the brewery uses leased kegs like micro star they can't give them to you. Both the kegs I got (from separate places) had the pickup tube broken off on the inside. Seeing as I'm just cutting the top it makes no difference to me, but I guess isn't worth the labor to them to fish it out. Another word of advice is actually go face to face and knock on the door, if you call they may just think your a guy looking for scrap metal and tell you they don't have any. Good luck.
