Eheim has had a solid rep for a long time, all I use, I figure that part of my system has been worked out w/ little left that could be improved on.
The Oceanrunners were good for the money too, and like Marlin said actually a tad more efficient, but they are bigger, and I know they either stopped making them or I think someone was going to take over that design going off vague memory/hearsay.
I would stick w/ that 1262 and focus on other gear, wait for feedback on the new pumps coming out and see how they stand the test of time(which Eheim has already done)
I also agree w/ only using return to carry water from sump to display, 3-5x turnover seems best, dwell time for skimmer, less chance of micro bubbles, and prefer low flow for fuge.
There's a fine line between owning your tank, and having your tank own you!_________________________________________
