A few years back when I was in college I was an accountant for a company that sold Point of Sale machines and their software.   I couldn’t believe how much they cost and how much corporations and businesses would spend just so that they could operate.   

Then there was the monthly licensing fees that also cost an arm and a leg!

The way to go is with a used point of sale system.   You get all of the features of a system but without the cost of it being new.   Typically, the hardware comes out with new models each year and there are many companies that go through equipment just to have the newest thing.

Therefore, many times a lot of good and used equipment gets traded back.  Ibm pos equipment seems to be pretty popular because of the dependability of IBM.    You can always get tech support and many times you can still find the hardware for the older IBM products.

Fujitsu Point of Sale equipment are also notorious for quality machines that will last forever!

Why buy new when you can get the exact same machine used for a fraction of the cost?
