The guide at the bottom of here might help picking a model out, though there is no guarantee that they will be in your price bracket in your region.
That is a pretty useful guide. I think however that the "top" players like the CLD-97 and 99 still fetch a high price on ebay.
You might want to look for the CLD-1010, a player that supposedly has a good picture but can be picked up fairly cheaply.
