Iwaki WMD vs MD
 

Hi guys. I have a question about the Iwaki's.

I need to upgrade my pump, since I'm putting more blocks in seriel on (across two computers) and running two large HC's in parallel in an external enclosure. I've decided that the best pump for this would be the Iwaki 20RZT. I have no qualms spending over $100 on a pump, especially on one that allow upgrades later.

I understand the consensus is that the MD is way better than the WMD, but haven't seen any data. Does anyone know the specifics?

What are the temp differences?
How much louder is it?
How much more reliable is it.
It's external, so I'm not worried about the size.

I just need to be sure that the MD is worth the $50 extra.

If I'm correct the japanese motor (MD) runs quieter and adds less heat. Thats it, oh and its about 30 bucks more..

From the two e-stores I've seen, it's $50. If it were $30 I'd just do it!

What e-stores are you looking at?
