Having difficulty deciding whether to go for the new Big Steel Keg (BSK) at $599, or try to score the old Bubba Keg for $299 from Home Depot (they are currently priced at $449, but others have reported finding them for $299). The Keg will be my primary cooker for BBQ since I have two other grills that can handle high heat duties, and with the vent changes that have been made to the BSK I'm wondering if it is worth the extra cost. Has anyone cooked on both, or have any information that might help me out? I've read too many posts on the bubba board about low temp problems on the original keg, and I don't want to be the next guy posting the "help - what am I doing wrong" message.
