The 74 is 13" touch screen only. The 52 can come with either a 15.4 non touch or 13 touch. Some good deals can be had on them if you check on eBay regularly. Just don't ever buy anything from "techforlessusa".

I have an old cf 28 which is the series you see in most law enforcement vehicles that I bought cheap that we used in the grain cart last year but now the hard drive is going bad and also a cf 18 tablet that we mounted in the grain cart tractor this year to record loads out of the field. Yes, I'm a fan of toughbooks.
