Alkyd has solid advantages overriding the slight cleanup in-convenience. It is exceptionally tough and very resistant to scrubbing. It stands up well in the trouble spots - trim, bathroom, kitchen. And it is easy to apply, producing a smooth, even finish free of streaks and brush marks.
Alkyd is an old interior paint made newly popular by a change in solvent - a super-refined petroleum chemical that has almost no odor. It is not a water paint. You thin it and clean brushes with mineral spirits or turpentine, or, if you want to retain the odorless feature, with the new odorless solvent. (Ask the paint-store man for just that, odorless solvent).
If you are going to paint your home and have decided to do it yourself take a little extra time and spend a bit more money to do it right. Colors are subjective, but the quality of materials and painting tools are not. For this example we are going to go through the process of painting the interior of a typical home. In just about every paint job I did I insisted that customers used an oil based paint on woodwork and doors. Not only does oil paint make wood look and feel better it gives you a superior durable and washable finish that water based latex paint can't. There is nothing worse than seeing a newly painted door or frame ruined by fingerprints and other marks.

Consider purchasing a hand held paint caddy and use it instead of a regular plastic quart. They are easier to maneuver with and usually come with a strap to attach to your hand.
