Quick Take
Data acquisition recorders can look completely different depending on what you're trying to capture. Do you need a component you can embed on a custom circuit board, a network-connected hub for energy monitoring, or a benchtop instrument for a lab? The four recorders here span exactly that range, and the right choice depends on your application, form factor, and price range.

Product Notes
Axon Instruments Digidata 1320A 16-Bit Data Acquisition System for pClamp Lab
The Axon Digidata 1320A is aimed squarely at electrophysiology and patch-clamp recording, listing pClamp software (Clampex and Clampfit) as compatible. At USD 99.99, it gives you a used 16-bit system from a United States-based instrument line. If you already work in a biological laboratory and need acquisition that ties into pClamp, this is the only product in the group with that explicit software match. Its stated intended use is biological laboratory application, so it may not be the right fit for building automation or industrial data logging. The used condition also means you should be comfortable with pre-owned lab equipment.
Maxim MAX126 2x4 Channel 14-Bit Data Acquisition System IC, SMD
The Maxim MAX126 is a surface-mount IC, not a standalone recorder. It lists as a 14-bit data acquisition system with a 2x4 channel configuration and an MPN of MAX126CEAX. At USD 17.35, it's the low-cost way to put data acquisition on your own circuit board. The condition is listed as new open box, and the listing notes that multiple parts may have different markings or date codes but should be in similar or better condition. Because it's an IC, you'll need to handle layout, power, and signal conditioning yourself.
DATAQ INSTRUMENTS DI-730-EN-A DATA ACQUISITION SYSTEM
The DATAQ Instruments DI-730-EN-A is the highest-priced item here at USD 1,000, and it arrives as a used system. The listing describes a power supply fan that makes a little acoustic noise but says the system works fine, and it will include grabber wires, though not the full set. If you want a complete data acquisition system with a brand-name manufacturer and an integrated housing, this is the expensive, used option to weigh. The fan noise and the incomplete grabber wire set are two details to factor into your decision.
Obvius A8810-0 AcquiSuite Embedded Data Acquisition System With Manual
The Obvius A8810-0 is an embedded AcquiSuite data acquisition system priced at USD 500. It is listed as new open box, comes from the United States, and includes a manual. The product description positions it as an energy monitoring hub with ModBus/TCP/Ethernet, so it's aimed at IP-based applications like enterprise energy management or smart grid programs. The main limitation is that the 24V power supply is not included, so you'll need to supply that separately. If your project involves collecting energy data over a network, this embedded hub is a targeted choice.
Final Recommendation by Use Case
If you are designing a custom board and want a low-cost component to integrate, the Maxim MAX126 is the direct pick. For electrophysiology labs running pClamp, the Axon Digidata 1320A offers the only explicit software tie-in. For a building or energy management project that needs an embedded hub with Ethernet-based ModBus, the Obvius A8810-0 fits the bill, as long as you provide the 24V power supply. And for a full, brand-name instrument-if you can live with fan noise and a partial wire set-the DATAQ DI-730-EN-A is the complete system at the top of the price range.
