Yeah, I'v had the dump, and the recirculating housings. As already mentioned, they just need to be cleaned up a little bit, and the gaskets shouldnt be used.
For $65 (compared to 250+) I think they are very nice..I wouldnt hesitate to use it if your on a tight budget like I am.
I believe these are the same ones beaner (from here) sells. Thats where I bought my first one.
