ION USB Turntable looks good. It will even convert 78s. I suppose it's only number crunching but us old analogue guys still think the modern world is full of witchcraft. Tee Hee.
Seriously thoughDO DO DO use a 79 stylus the modern stereo ones will chew up your precious 79s.

Oh by the way I wash my old L.P.s as above but then play them as wet as possible (mind the 'lectrics) The results are sometimes magical, the stylus just seems to float over the scratches.
