When you're shopping for a data acquisition recorder, the name on the front panel tells you less than the extras around it. Two units, the DATAQ DI-720-USB Data Acquisition System w/ DI-5B Amplifiers & MESA Interface and the Vector GL2000 CAN/LIN Data Logger with VoCAN Voice Control & Flight Case, come with similar price tags but different personalities. One is a bench project; the other is a carry-along logger. The real question is how you want to spend your time: tinkering with a surplus unit or carrying a clean logger to the job site.
Quick Verdict
The Vector GL2000 is the safer pick on first impression. The DATAQ DI-720-USB is the better starting point for a hands-on project. The choice hinges on whether you value convenience over involvement.

Where Each Product Wins
The DATAQ DI-720-USB is the project choice. It suits a buyer who enjoys tinkering and has the patience to verify the unit. The Vector GL2000 is the package choice. It suits a buyer who wants to start logging with minimal fuss. One will take more of your time; the other adds convenience.
DATAQ DI-720-USB Data Acquisition System w/ DI-5B Amplifiers & MESA Interface
This DATAQ unit comes from a university surplus environment and was visibly dusty when found, so expect to do some cleaning before it looks at home on your bench. It is sold as-is and untested, so you'll need to verify every channel and amplifier yourself. The upside is that the DI-5B amplifiers and MESA interface are included, giving you a signal-conditioning front end that you don't have to source separately. If your application relies on those amplifiers and you're prepared to troubleshoot, this is the more budget-conscious way to get that functionality.
Vector GL2000 CAN/LIN Data Logger with VoCAN Voice Control & Flight Case
The Vector GL2000 presents itself as a clean, well-cared-for unit in excellent physical condition. It ships with the VoCAN voice recording and control remote, which can be handy for time-stamping or noting events during a logging session, and a hard shell carrying case for transport. The unit was made in Germany and shows minimal signs of use. Keep in mind that it is also sold as-is, so even a clean exterior doesn't guarantee operation. If you're comfortable with that caveat, you're getting a well-presented logger with useful accessories and a much lower risk of surprises than something that arrived dusty and untested.
Final Choice by Use Case
If $349.99 fits your budget and you're setting up a lab station where you'll do your own troubleshooting, the DATAQ DI-720-USB is the lower-priced entry. If $399.99 seems reasonable and you want a more complete kit from the start, the Vector GL2000 is the higher-priced but more inclusive option.
