i think any thing more than $1-1.50 pound is to much but then i'm a little cheap the ones i have bought for me or my friends never cost more than 1 buck a pound if you were in jersey i could put you on to a guy that has a few anvils inthe 100 - 170 pound range most were under the 200 range
the best advice is to tell every one you meet that your looking for anvil and such you never know whats kicking around in ones shed, barn, garage,and yards
