I'm not surprised that you don't get depth of field in scanner specifications, they are not designed for 3D objects and I feel you were lucky to find one in the past that did this for you.
Having said that, I know they do, or did, exist because I remember several years ago on QVC that they made a point of one of their scanners being able to scan 3D objects. I can't remember any detail at all but, QVC tend to sell items from the same manufacturer for years on end so if you look on their website, you may be able to find a possible producer and take it from there. Remember that QVC have a 30 day no quibble guarantee as well!!
