My son goes to the new Junior Village Preschool - the Bolingbrook location. It's off of Boughton near the Meijer on Webber. It's a fabulous program and very affordable. We live in Naperville too. I currently pay $155.00 a month for the 4&5 year old class. It meets 3 days a week. If you are looking into the 3 year old class I think it is a little cheaper - I believe around $140.00. One way they are able to keep the costs down is by having each child take turns bringing in a healthy snack once a month.
Honestly, I was hesitant at first because it is so much cheaper than the other preschools in the area but after finding out about their program we decided to give it a try and I am very happy that we did. My son loves it and the teachers are super! They have a fantastic phonics program. My son should have a very easy transition to kindergarten in the fall thanks to his teacher and the preschools curriculum.
I hope this helps!
