I second the ebay suggestion. I scored a 5-faucet ceramic tower for about $200. I'm not saying you're gonna be able to get a tower that cheaply, but there are deals to be had. If ebay is not your thing, then a couple of the online sources are good. Micromatic.com is cheaper than northernbrewer.com by about $10 on the stainless steel towers, but make sure you take into account shipping costs when comparison shopping. I would say that the difference between chrome vs. ss vs. brass is mostly aesthetic, so if it were me, I'd go with the cheaper chrome tower and upgrade the actual faucets to forward sealing faucets.
