Well, I wouldn't waste my money on a second one. If all of us that have had problems have got "duds," then it doesn't bode well for the quality of the manufacturer, and that would be another reason to avoid it.
The NPU-500's numbers that they advertise are understated. By high quality plastic I mean it is of the rugged variety, unlike what I've seen on most pumps (you can practically make a Via pump break by looking at it ... I destroyed many of the fittings with hand pressure, and I wasn't even trying). Besides the rugged casing, it also has a thick rubber grommet around the entire pump protecting it (and parts in you box) from damage in the case that it shifts around somehow. They built the things so rugged that you can drop kick them and they'd be fine. Even without all those things, it was the 2 year warranty regardless of use that attracted me. I could run coal tar through it, and if it broke, return it for a new one.
