Just one caution if you go Snap On, beware of the "K I Q" series of boxes. IF you are expecting top Quality this is not the one. I bought my top and bottom boxes 8 years ago for 1500 brand new and have been replacing slides ever since. There is a provision for doubling the number of slides on all but the 1.5" drawers which helps some. I buy the slides at the rate of about 10 pairs every 2 years. However, it was still worth what I paid for it. Good luck, David
