OK. I need to be careful! I'm finding these:

011012 IntelliFlo VF => IntelliFloŽ VF High Performance Pump
011013 IntelliFlo VS-3050 => IntelliFloŽ VS+SVRS Variable Speed Pumps
011017 IntelliFlo VS SVRS => IntelliFloŽ VS+SVRS Variable Speed Pumps
011018 IntelliFlo Variable Speed Pump => IntelliFloŽ Variable Speed Pump

P6E6VS4H-209L IntelliPro Variable Speed Pump => IntelliProŽ Variable Speed Pump
P6E6Y4H-209L IntelliPro VS-3050 => IntelliProŽ VS+SVRS Variable Speed Pump
P6E6XS4H-209L IntelliPro VS SVRS => IntelliProŽ VS+SVRS Variable Speed Pump

We need a comparison chart for these beasts, so mods and contribs can make good recommedations.
