Samsung Hd841 or Toshiba 4960 modifications

Can anyone give me some impressions on these machines? I currently have a much more expensive player. I like the fact that these players are universal, physically much smaller than what I have, and cheap(!). There is a very positive post here on the stock player, but if it is that good, why aren't more people jumping on board. Is it that good? Or just good for the money?
