Best prices for co2 tanks?

I tried the search, but didn't come up with any concrete answers.

Where is the best place to get a co2 bottle? Here in NYC you can't rent them, you have to buy them at full retail. You also have to trade them in when you get a fill. SO I don't want to pay the extra for aluminum. Steel (reconditioned) is what I'm looking for.

I need a 10# and a 5#. I found a deal on an aluminum 5# for $50. Can I get a steel one cheaper?

MicroMatic has a 5# al one for $57
Adventures in Homebrewing has 10# steel for $75


Does anyone know of any cheaper places?

And yes, I've checked ebay and craigslist!

Thanks

Micromatic has the lowest prices for a new CO2 cylinder that I've seen. I'd check craigslist...maybe you'll find one there for cheap.

Try ebay.

You can find them used and new for good prices. They will try to burn you with shipping, but ebay has supposedly put a lid on shipping charges now.

ETA: And yes, I've checked ebay and craigslist! Crap. Missed that part of your post.
