I was planning on trying their new Mag pump once it's out.
On laing pumps do you mean like this one?

They are small, but they are also so ugly, and the formed plastic won't allow for metal threaded fittings.
At $75 I would expect the ability to change the taps, or a more refined look.
Looking at the PDF's for that pump it looks like it wouldn't be out of the question to build a completely custom shell for the pump, getting rid of the cheap looking plastic.
