What ya got and why? I currently have 2 Eheim 1048's in serise feeding my RBX then to my PA120.3 rad. wanting to go to a single pump...been looking at the A50z or an Iwaki but they are £268 here in the uk!!!!
Go for either a DCC or D5 (or swiftech equivilants). The DCC is quiet, compact and packs a punch. The D5 is a beast but can be run at lower settings to get the best balance of flow and noise. Both are 12v so are more convenient than having an AC pump with relay.
I've got two CSP-MAGs, running side-by-side. Should have gotten a DDC, but that's water under the bridge. I got two of them for redundancy, and a totally rediculous flow rate.
A single Innovatek HPPS with an attached Tank-O-Matic plugon reservoir. Why? It's quiet, the ressy is connected, makes filling/bleeding easy and it looks nice.
A Davies-Craig EBP. Why? Because it was built to withstand rugged environments, has a long MTBF and basically was one of very few 12V pumps on the market at the time.
DDC12VPLUS1 with plexi top (using top inlet) Nice pump, solid flow, not too pricy, looks cool, needs really good anti-vibration though or it makes the whole case whine
