Buying used can save significant money, if you have the time. ("save"? who are we kidding - that "saved" money will just go toward a better machine or more tools)
For example, it's not unusual to see bandsaws with broken trunnions, rusted tables, dead motors, or missing minor parts being sold almost as scrap. Many popular models have after market trunnions that are simple to bolt on, tables can be sanded clean, tires swapped, and minor parts replaced or 3D printed. Most of the machine is not that complicated - even an out-of-production motor can be rewound or a replacement adapted. Just be sure you know what you're in for in terms of time, complexity, skills and money to repair an ailing machine.
With any used machine, it's worth downloading the manual and giving the machine a thorough going over, cleaning, tightening, truing, and fixing. For example, sawdust buildup can throw the wheels out of balance or a misaligned table throw off your cuts.
