Here is a before and after of some side tables my friend gave me.  I didn't realize until after I painted them that they needed a good sanding.  Luckily it's just my Husband and I who will ever really see them.  Maybe I'll fix them up in the summer.  For now I am just really happy with them.  We have been using some really small mosaic tables for the past 6 years and these work MUCH better!
