Needles for just about any turntable can be found at Garage-A-Records (http://www.garage-a-records.com/). I have been buying from them for years. I buy old turntables at thrift store, flea markets, etc and restore them and re-sell them so I use the guys quite regularly.
My preference is the Dual 1019 with a Shure V-15 II with a JICO stylus (we have 4 turntables in the house and they're all the same set-up except for one that set up exclusively for 78s).
