Out of that group I would choose the Technics SL-1700 without a doubt. The 1200 is nice but bear in mind that they often pull DJ duty and as such have often seen heavy use / abuse. They also don't have any suspension, so resonance or feedback may be a problem. They are a full manual turntable, so you will have to retrieve the tonearm at the end of every play.
The SL-1700 has a suspension and an auto return, and it's a nice silent turntable especially for that price. I prefer the original version to the MK2 version, but that's just me. The Harman Kardon is a nice table too (made by Rabco I believe) but I've heard of some maintenance issues with it - maybe someone more familiar with it can chime in here.
