The best Duals are the 1229/1219, which are idler drive. Then the 701 direct drive and lastly the 1019 idler drive.
Google Dual 1229 extreme and then hit 'translate' I own a modified Dual 1229. I replaced the tonearm with a Grace 747. It's the finest table I've ever owned. I still have a very nice Garrard 301 with a SME tonearm. I personally love the sound of idler drive tables, with direct drive being next. They portray pace, and power that has to be experienced.
I sold off my kilo buck LP12 along with the Aristion RD 11. They are fine musical tables, just not for me.
I would recommend purchasing a serviced Dual 1229. You can find a few compaines that offer them.
With regard to the 1218, I would stay away from it. The platter is on the light side and the motor isn't the same powerful massive smooth beast found in the 1229/1219 tables.
