If you're looking to pick up a few kettles for smaller batch brewing, this seems like a steal: http://dealnews.com/-4-Piece-Stainless-Steel-Stock-Pot-Set-for-14-2-s-h/490524.html
It includes 6, 8, 12 and 16-quart stainless steel pots with lids, just over $16 shipped. None of the bells and whistles of a true brew kettle, but you gotta start somewhere.
Also, with the recent deal for 40% of the deluxe kit at Northern Brewer, you can get up and running fairly inexpensively!
I do mostly 2.5/3g BIAB batches in a 20qt kettle, but the 16 should work fine for your main brewpot if you're also in that size ballpark. So certainly not for everyone, but FWIW, thought it was a good heads up. I wish I found these two deals when I was starting with the obsession back in May
