Buy one. Since I bought my ULTIMATE stand (made in Canada), it has encouraged me to do maintenance I pushed aside for half a decade. The stand brings the bicycle up to eye level, so you can see into awkward places.
You want it up in the air so you can pull off the wheels. How are you going to do that on the ground?
If nothing more, a clamping stand assists you in washing your bike thoroughly. You can turn the bike upside down, for those nooks and crannys. It will set you back about $180. But, because my bike is a custom-made affair from England, it deserved good upkeep.
Ultimate stands are put on sale by the mail-order stores at least once a year. If you mountain bike, The TOPEAK is actually a better stand, but costs about $50 more. Many stands collapse, come with a carry bag, and can be tossed into a car trunk, so guys on a group ride up in the woods can share it.
