Perhaps an SACD player? Pioneer do SACD / blueray players for a few hundred quid and they are said to be good.
I own a Sony CDP-715E that I bought on eBay for £20. Cracking player which I prefer to the Marantz CD63KIS. There is a lot of good old players around and for me it's the only way to go. As said before consider the high end dvd players that have been put on the scrapheap for Blu-ray.
£50-£100 in the classfieds here on Epay. You can buy some very nice old CDPs (Sony ES) or DVDPs (Sony, Toshiba). Id certianly not spend more, you then have funds to imprtove speakers and amps dowen the line, in the scheme of things digital players are generally all pretty competent to my ears.

Unless you particularly for whatever reasons want an old CDP for 'nostalgia' causes, I advise buying the new one warrantied that you want/will love despite its being CD. I have bought-still enjoy 3 old CDPs replicating what I used to have from mid 1980s, and of all of the 10+ other stand-alone CDPs (+ about 20 others in music-centres-PCs), only a Kenwood 7090 failed after 7 years-a LG external CDRW failed after 2.0001 years.
