I have two bandsaws...A 15" Jet for mainly resaw/ripping and a10" Rikon for small stuff.
Bandsaws can be one of the most frustrating tools in a shop. While Alex Snodgrass makes it sound easy, sometimes not so easy. A used saw could be great or require new rubber wheels, alignment, guides, etc. If you have some experience with a bandsaw and are handy with machines, then used is great.
Personally, I am at a point where I want to use a machine and not spend a lot of time fixing it.
