When you spray inside, there is still a lot of prep to do. I'm sure you know you have to cover everything you don't want paint/overspray on with plastic, drop cloths, tarps, etc. You will most likely need to tape up plastic sheet from room to room & over the other spaces you want to prevent getting paint on - and you will get overspray through little places you missed sealing completely. So putting it up, taping, taking it down, redoing it as you go along eats up a lot of time & is OK for large areas but not for smaller ones. Those cabinet doors & drawers probably should be sealed and sanded over to get a decent surface finish. Truthfully the power roller idea is likely the best for the walls and some good paint brushes (3/4/2/1 inch) will also likely be faster and better than spraying the cabinets & drawers. You will still have to remove the drawers & cabinet doors and remount anyway whether spraying or brushing. Remember you will also have to do touch up after spraying, whereas with the rolling and brushing process, that's kept to a minimum. If you just absolutely have to resort to spraying, renting is the way to go for you. You also need to do a thorough job is cleaning the sprayer afterwards too. $250/$300 won't get you much of a sprayer. The diaphragm kind are only good for 300 gallons on average until you have to get another one. There is more to spraying than sticking a siphon in paint and pulling a trigger.
