Remanufactured toner cartridges – worth it?

Our LaserJet printers are way past their warranties so I’m looking at going from HP toner cartridges to remanufactured toner. Here’s some pricing I found:

Item: C8061X for HP 4100 LaserJet

HP New: 119.95
Rhinoteck Remanufactured: $86.21
Xerox Remanufactured: $79.30
Radian Remanufactured: $72.55
West Pint Remanufactured: $61.05
Verbatim Re-manuf: 57.95

Okay, so why is there a 48% price difference between the Verbatim and the Rhinoteck? Is this going to be one of those “you get what you pay for (or not) things”??

Anyone have recommendations or experience they can provide?
