Just seen these two in a second hand shop SONY MDS-JB930mini disk & SONY CDP-XB930E cd player , both are in v good condition with boxes but no remote controls , and Ive tried them out, both seem to be OK . The shop is also offering a 3 month money back warranty. How much are they worth?? Are the worth £150 if so I'll go back and get them. Daran.
