Dual 1229 Turntable OR Kenwood 5070 ?

Without a doubt, take the Kenwood

the Kenwood over that Dual any day that is one of Kenwood's better tables you'd have to spend quite a bit of cash to get the same performance in a new table. The Dual is ok for what it is but i don't think it stands up to the Kenwood.  

Dual, way too many moving parts will need service, idler drive can be an issue. 

Kenwood, direct drive so no belts, idlers to worry about. much better arm. 

The Dual is capable of sounding very good but if not done already will need a service. I've not heard the Kenwood. If you are not a vinyl man, the Kenwood might be less stress but I can't imagine it sounding anywhere as good as this classic Dual.
