If you're choosing between two used lab balances for your laboratory, the decision usually comes down to how much capacity you need, how fine a readout you want, and how much prep you're willing to take on. The Mettler AE 100 and the Ohaus SPX2202 sit at different points in the lab balances and scales landscape: one is an analytical balance built around smaller samples, while the other is a precision balance.
Quick verdict
If you want the lower listed price, the Mettler AE 100 at $150 is a workable analytical balance, as long as you're comfortable with a used instrument that needs attention. If you want a tested working balance that's ready for routine lab use, the Ohaus SPX2202 at $206.15 is the stronger pick.

Product notes
Mettler AE 100 Analytical Balance
If you're comfortable setting up a used instrument, the Mettler AE 100 is a solid fit for analytical small-sample work. It remains functional, but you will need to plan for calibration before relying on it for precise measurements. It shows scuffs and blemishes, and calibration weights are not included, so your lab will need its own weights or a calibration service. For a bench that already has a calibration routine, this balance can be a practical way to add analytical weighing without the expense of a new unit. If you need a ready-to-use balance, this one will ask for extra effort.
Ohaus SPX2202 Precision Balance
The Ohaus SPX2202 Precision Balance brings generous capacity and fine readability to routine lab weighing. It was maintained on a regular annual calibration schedule while serving in a research lab, and it has been tested working. A digital LCD display delivers a clear readout, and fast stabilization helps keep weighing moves efficient. The trade-off is that its calibration certification is no longer current because the unit was removed from service, so you'll want a fresh calibration before using it for critical measurements. For a lab that wants a high-capacity balance with fine readability and a service history, this Ohaus is a strong candidate.
Final choice by use case
Choose the Mettler AE 100 if your work is analytical and small-sample and you're comfortable preparing a used instrument for service. Choose the Ohaus SPX2202 if you need to weigh up to 2200g with 0.01g readability for routine lab tasks.
