A lot of people use this:
Bikemate Bike Assembly Stand - ALDI UK. I think I bought mine for $20-$25. Amazon charges more for what looks like the same stand.
I wish it required less floor space, but I have to use it in the foyer of an apartment. If I had a basement or a car space in a garage that wouldn't be a problem. I wish it were more stable, but that comes at a price I don't want to pay. It's OK, but for bottom bracket work, I put my bike on a trainer and sit on the floor.
