I have one of these:

and a colour Boox. The refresh on the Boox is so fast, you can watch video.

I don't think the Meebook has refresh issues, it's definitely very fast for back/forward. Of course I don't have page turn animations on. I use the kindle app on it, and KOreader. If you get this, know that there is a thread to drop in a script, so the volume buttons page turn correctly when upside down.

If you live in Amazon turf, you can always buy and return if not suitable?

There are some reviews on Amazon.
