I would check three things before buying.
First, don't buy a direct drive machine unless you get it for half price and really want the machine. Cutter heads cost significantly more for this method if you need to repair or upgrade. If the motor is mounted low with a belt drive-you are good.
Second, I would make certain the in-feed table isn't dished. This is common on heavily used machines--scratches and shallow grooves are common and don't interfere with operation. There are so many of these out there I would wait for one with flat tables and less wear than take a dished machine.
And finally, if it is a later yellow machine, check the tags to make certain it doesn't say made in Taiwan.
One more option is segmented roller which is a plus but not a deal breaker.
Stick a Byrd in this planer and you will be impressed with how quiet it is!
Best,
