I don't agree that you get what you pay for, because my 3 boys went to a very reasonably priced preschool, with a high quality program. There was a very low turnover rate of teachers, many repeat siblings, lots of crafts, and very happy children.
However, in your situation I would look for something that is a higher quality. When I looked at preschools I saw all kinds of things, including one preschool teacher who wanted to chat with me, so she put the tv on for the 3yo's and insisted that they all sit and watch it. The other places I visited made time to answer my questions, but in between time doing art projects with the kids, etc. IE, I was the one doing the waiting, which is the way it should be.
Good luck with your decision!
