I wouldn't touch a used one for $150 as it is a given that it is going to crack. Just a question of how soon, and there's nothing you can do to prevent it.
I did a lot of calling around many years ago about this and wrote it up while still on FTE. But you can read a bit about it and get a link to the FTE writeup
here.
My current thoughts are that the dash covers from Coverlay, which is what all of the vendors sell, is very good and it is what I'm running on Big Blue. But for Dad's truck I'll probably go with the high-end, like Dashes Direct. However, I won't buy it from them as it is cheaper to get it from one of the resellers, like JBG, LMC, etc.
As for LMC not having them, check with all the other resellers. What they are selling is the same - Coverlay - so you can get it lots of places.
