If I were you I'd ask the seller if he could just take the pics in complete darkness. And that way he could say it is made of GOLD to!!!:gringreen
Before you waste your time, tell him to take some better pics and send them to you. If everything looks good then go have a look see. Check the impeller shaft for movement. If there is a lot of play there you will need a minor rebuild (bearings and seals). If it's all there like he say's "it could be a good deal" for $600.
That looks like an old SN93 model, and if it is it's most likely in need for a complete rebuild. Nothing at all wrong with a Paxton, and for $600 it's not too bad considering the condition it's in. Question is are you willing to do what it needs to get it in running condition again?
If it can add 8 psi like he claims, you'll go from that 230 up to 310-315.
