Got me a Park tool repair-stand some weeks ago. I now have personal experienes to share:
If you have good intentions of keeping your bike well lubed, clean; or doing repairs;but are hesitant doing this because of tediouse nature of this; a repairstand will help out.
A repairstand helps you get your bike in a ergonomical correct height (you can stand raised; working the top half of the bike and perhaps sit on a stool for the bottom-part of the bike). This in its own right was a motivating factor for me.
Secondly; having the wheels float in the air thus being able to turn is a big advantage; as cleaning and lubricating the wheels, chain & sprockets is made much easier.
Knowing this from the start; I would have bought one two decades ago ! One of the most sensible bike-accessories I have ever brought home. This was my 5 cent in the matter ;-)
If you plan to purchase a repairstand; make sure it is sufficient to your needs; in terms of weight-limitations/ that it will carry your heavy-weighter, how wide tubes the stand will grab around and what kind of stability of the stand you demand.
In general; go for a quality stand. Your bike is probably worth it ;-)
I added some padding where the stand grabs hold on the bike, for peace of mind ;-) The stand holds securily on to the bike. The stand I choosed; tolerate my Stromer; including battery. But by removing this; several kiloˋs are shaved of the bike;making cheaper stands adequate.
The stand is also very compact when folded together. I keep it on a shelf in my garage.
Made some pictures for you:
