The best are the CDJ-1000 models, but he'll be just fine with an entry-level model such as the 100S. 400 and 800 models are midrange and nice too. Check EBay, there are tons of options available. Good luck.
Although it would be very remiss of me not to suggest you buy him a couple of new carts for his 1210s instead and get him spinning again the way choons should be done.

I would have loved to get him some pioneer 1000s, this is what i started out looking for, but just a little out of my price rabge!! beyond pioneers im very confused! The 100s are definately affordable, but will they be good enough? Thet look quite easy to use too. We do still have the technics, and mixer which is Gemini pmx 140, would this be compatible with pioneers? Its just not worth replacing needles and carts on the technix because his vinyl collection is so out of date, he'd need to spend so much money on this too, so he might as well just start with cds/mp3 as this seems to be the future. Will the 100s use mp3? Thanks for all your helpfulness!!!
