Added thought: For that type of power, why not use IGBT? I know you have the mosfets already, but they might be used for something else. I got a couple of these (cm400du-12f) for about $10 each on ebay.
If you search on Digikey for SOT-227, you will find a lot of transistors in that package. A lot are $20-$40 each. That $120 might be because it's now an obsolete part or something. The company called IXYS seems to make a lot of them, as do Vishay.
