Decanter Recommendations?

[Triple H]

I've finally realized I need to get a Decanter, but I'm not sure how to proceed. The price ranges are staggering, and in reality I wonder if that old glass "Wine Carafe" I own would do the job just fine? The other option seems to be the "broad base, thin neck" style, but of course that’s where the price ranges come into play. So I guess I’m asking what you all use, are you happy with it, and what did it cost?

Thanks Much!
