...I just saw a WMD30RXT for cheap ($20), so I was going to snap it up. Instead I'll find another cheap pump.

Note that you do NOT want any of the "WMD" model pumps - there is a reason why WMD's are cheap...
As I understand it, IWAKI pumps come in two flavors, both use the same pump head for a given model number, but the motors differ.
"MDxx" models use a Japanese motor, "WMDxx" models use an American motor. Aside from Iwaki itself, I have never seen anything positive said about the American WMD motors beyond the 'Made in USA' factor. OTOH, I've heard that the WMD motors don't have the same reliability and quiet operation that the Japanese motors do. Judging by the pictures, I think the WMD motors may be slightly larger as well.
Just remember - WMD is bad, MD is good....
