In that price range my choices would be the following, Please keep in mind I prefer a London Pattern Anvil because I forge a lot of different things.
1). Kanca 110 drop forged anvil $640 delivered to your door. Link:

2). Emerson 100 pound traditional anvil with turning cams $810 delievered to your door. Same site as above
I have also been researching Holland anvils which are made from H-13 steel and have a good reputation on the forums. They are currently out of stock on everything in your price range but I would surely look them up when you are ready to pull the trigger. I have my eye on their big Sawyers anvil too.
Remember the main reason for getting a heavier anvil is so you can use larger hammers on them. The general ratio for hand hammers and anvils is about 50:1. A two hundred pound anvil will love a four pound hammer. Yes, the work area is larger, but the main reason for the expensive 300+ pound anvils is so you can swing BA sledge hammers on them. If you are like most other people (myself included) I mostly swing a 2.5 pound rounding hammer and sometimes a three pound straight peen. I have a 140 ish Peter Wright which is what I need. If it did not have a sway in it (which Peter Wrights are known for) I would not want for a new anvil. No 300 pound anvil needed.
For about half or less of the cost above, Boss Dawg has the Black Robin (knife work only) or the NC knifemaker anvil. I have not used either of those but I know guys using the NC anvil as teacher anvils in their shop and they like it.
There are other anvils out there but for the money those are MY choices.
