What to you intend to do with the stand? If it's just chain lubing and minor adjustments go with the cheapest stand you can find or just hang the bike from an overhead rope or hook. If it's complete overhauls or building a bike up (or back up) from scratch including bottom bracket and headset work, a high quality stand is a must. You don't have to go for the heaviest or most elaborate but get a solid stand that holds the bike firmly and lets you access it from various sides and angles.
