You could still go with the low-tech, low-maintenance approach, that's cheaper!
A good "cheaper" alternative to the Eheim Pro III is the Filstar XP3. The XP3 has fewer bells and whistles and draws a bit less than twice the wattage, but I've been pleased with my two and wouldn't pay $160 more dollars for a priming button and a flow indicator, that's for sure!
Now I'm curious to see how long it would take for the lower power requirements of the Pro III to break even with the 2x price difference. If my calculations are correct, with electricity at 10 cents/kWh, the XP3 costs about $26 a year to run, while the Pro III costs $14 a year. It would take about 13 years to break even.
