Choosing between the Vector GL1010 Compact Data Logger Module and the Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System comes down to how much data acquisition capability your bench really needs. The two used units are separated by more than a thousand dollars, so the right pick depends on the scale of your measurement work and whether you expect that work to grow.
A simple logging task can be served by a compact module with minimal wiring. A more demanding test setup may need a mainframe with room for multiple modules and multimeter-style measurement. Knowing which camp you fall into makes the choice much easier.
Quick verdict
For a straightforward logger module, the Vector GL1010 is the sensible choice. For a more capable acquisition system, the Keithley DAQ6510 earns the larger budget.

Product notes
Vector GL1010 Compact Data Logger Module
The Vector GL1010 works well when you need a tested data logger with a modest footprint. The seller describes light lab use and good condition, and the unit is confirmed working. It comes with a USB cable, so you have a connection path right away, and the module design keeps the setup simple. The limitation is the missing D-sub connection: only the USB cable is included, and there is no original box. If your workflow depends on D-sub, you will need to supply that link yourself. For small-scale recording tasks, this module is the practical starting point.
Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System
The Keithley DAQ6510 is the stronger candidate when your measurement needs are expected to grow. Its two-slot design gives you room for additional acquisition modules, and that expansion capacity is a major reason to choose it over a single logger. The seller also notes that buyers are responsible for customs charges, taxes, and duties, so international purchases require planning beyond the initial outlay. The seller asks you to confirm the item can be imported before buying. For a bench that will take on more complex acquisition jobs later, this system gives you room to move.
Final choice by use case
Choose the Vector GL1010 when you need a data logger for straightforward recording, want a simple connection path, and prefer to keep your investment at the lower end of the price range.
Choose the Keithley DAQ6510 when you need expansion room in a data acquisition system and can handle the larger investment along with potential import duties.
