I have a Swiftech MCP355 for sale at $35 + s/h. The pump works fine but It has a forced screw in one of the corner holes that was secured by its original owner by a series of washers. The pump also has an adhesive foam pad applied to its base to prevent vibration. If you are interested, please PM me and I'll give you pics. We can set up an private eBay auction for proof of purchase too
