There's only two pieces of equipment you need to use NeuroLister (and both are optional for some sellers):
Label printer
Barcode scanner.
Do you need a label printer?
Only if you're an FBA seller.
Do you need a barcode scanner?
You can theoretically type in ISBNs/UPCs manually, but it is not recommended.
Label printer: Understanding your options
NeuroLister works with the three main label printer makes:
Dymo
Zebra
Rollo
Each of these has several models to choose from. And all of them can be found used on Ebay or Amazon (these printers can last for a decade or more, and there should be no issue buying used.)
Personally, I (Peter Valley) have used a Dymo LabelWriter 450 for many years, and have always found it reliable.
Barcode scanners: Understanding your options
If you have a portable scanner you use to source inventory with your smartphone, you can connect that to your computer.
Most sellers prefer to have a desktop scanner dedicated to listing.
There are many options that can be found for as little as $30. Here is one I use personally.
What about FBA labels themselves?
These can be found for very cheap on eBay.
