Welcome to the forums. This may sound confusing, but both the preceding guys are right, just from different angles. If you are looking for a new anvil, yeah they are pricey, and two to three dollars a pound is pretty common even for used anvils. However, deals are still out there to be had. The keys are patience, and ummm.... well...obsession.

Look anywhere anvils might be lurking: antique shops, flea markets, junk shops, junk yards (especially with scrap metal being so valuable these days...), yard sales, news paper classifieds, local classified publications (up here we have the Paper shop, and Want Ad Digest.. you get the idea), auctions, Ebay. Ebay is a good place to look at a lot of anvils and get a feel for what you want, and what things are worth (though they fetch top dollar on Ebay).
Put the word out to friends, family, co-workers. Tell everybody you know. You never know whose grandfather or dad has an old anvil out in the barn or basement that is just "in the way".... Check out anvilfire.com for local blacksmith events, they always have a swap meet going in the parking lot.
If you really want to get forging, don't hold back waiting for the perfect anvil. Find a flat peice of steel and have at it. Lots of us started out on a piece of railroad track or a cheap chinese "anvil shaped object". Lots of us have made our own out of a big chunk of steel in a bucket of cement or whatever.
Just keep your eyes and ears open. Maybe post a wanted ad in the paper or on craigs list. I guess I just didn't want you to get demoralized by the two to three dollars a pound thing. You can defienately pay that, however I have five now and I haven't paid a dollar a pound yet. But then I love "the hunt". Thats part of the fun for me, finding and getting " a deal".
Whatever you do,
good luck and most importantly
HAVE FUN!!
