430 Sterling = 674USD.
For this price the lens should be basically perfect.
I think I paid 650USD for mine less than one year ago LN. I bought it here, if I remember.
Regarding the zeiss "wobble", my impression is that it is the same as the Leica wobble, which is actually very common.
While my zm35/2 is tight as a tick, I had to send both my 28 cron and 21 SEM to DAG to fix wobbles. He sees this often. It's a very simple matter to fix, not expensive, and i would never send a lens back to zeiss, frankly for this or any reason unless there was a warranty involved and I did not care if the lens was gone for months. Same goes for Leica.
DAG is at the top of his game and highly professional with fast returns on these repairs in the last year. There are several other good techs in USA too, but I would trust DAG over Leica without qualms. I'd send any zeiss lens to him as well.
For the OP your lens is not worth more than 300USD, if that. I certainly would not buy such a lens. However, I have often received lenses not as described and negotiated a fair price instead of return, so it is certainly not a silly course of action.
But the ZM 35/2 is a common lens and easy to find perfect under 700USD, so why play around?
The wobble comes very easily to a 28 cron or SEM 21 (along with the ZM35/2, two of the greatest lenses ever made for any system), especially if you use the Leica leather case with the hood "down". Never allow these lenses to travel with the hood under the mount, period.
When mounting, never grasp the front of the lens, but hold it near the base.
Follow these simple rules and the Leicas will stay tight.
