We are going to buy for the 1st time and don't really know what to look for. Anybody buy a rebuilt as opposed to a new? advantages/disadvantages?
Rebuilt engines are "usually" OK, but a lot depends on who did it, and what they used for parts. Lower end parts will be not as good as the original factory parts, higher end stuff can be considerably better than OEM parts. If you can some info on who rebuilt it, you can do some research into their reputation, and even talk to them about what parts were used.
The best rebuilt engines are often ones where the original engine was rebuilt for the van owner. Usually, it would be because the engine just got tired, not run out of oil or overheated, like many of the off the shelf ones might have been. They are often not bored as much over, or machined heavily in other areas to fix problems, so they should hold up better. On any rebuilt, I would have a good mechanic do a compression and leakdown test on it as that will tell a lot about the condition. Actual oil pressure is also useful.
New factory engines are a lot more predictable, middle of the road quality wise. They are a bit spendy though.
