I used to have one of those and IME the paint fades over time and they end up looking pretty fake. I think the large ornament in the second link is the same one I had, and if it is then watch out! My ornament was hollow and I had a few fish actually go inside, and maybe a couple die in there too (it was back when I was a total NOOB). Those ornaments are pretty expensive, why not just grab a nice piece of real driftwood from your LFS, or order one online, for roughly the same cost?
