A bandsaw is relatively simple, but requires a thorough and accurate setup. Tracking the blade, adjusting the guides and proper blade tension are the main issues.
Bearings usually last a long time and are easily replaceable with some mechanical knowledge.
Blade guides are hard to find if they are missing or broken, but not impossible. E Bay is a good source for older parts and new.
Belts and motors are basic machine parts and easily repairable or replaceable.
The brackets that hold the table in positioin, trunions are one of the weak links and should be checked for cracks. Do not move a bandsaw with the table in place, it may tip and crack off the trunnions.
The two types of bandsaws are a welded frame like the newert Craftsman, Grizzly, Rikon, and Lagunas OR cast iron frames like older Deltas, Grizzly, Jets. It doesn't really matter which type you have or buy, they are both good. A cast iron fram can be extended with a "riser block" for additional hight under the blade for resawing thick stock.
Blade guides are of two types, those that spin, like roller bearings or discs OR solid material like plastic, hardened steel, even hardwood.
They just keep the blade in place and are not meant to press against the sides of the blade with any force.
Grizzly has many videos on their specific machines and how to set them up:
