I loved my MR-2R...
Becketts work great when they are dialed in. I just needed to cut back on my fish costs.
Pump to drive beckets at 275 watts.
275*24 hours = 6600 watss a day
6600 watts a day * 365 = 2409000 watts a year.
2409 killowatts * .095cost per kw/hr = 228$ a year to run
Most the Needlewheels are less than a 100 watts, which will run you ~83$ a year.
