Don't forget that you also have shipping to pay on top of that 200. I just today sent my 2.8F to Fleenor and shipping with insurance was over 60 dollars each way by priority mail or 25 dollars one way by parcel post. Fleenor won't use parcel post to return. I don't believe that the Xenotar vs Planar makes much difference especially in that model. You can make a study of completed listings on ebay but personally if it was me, I would just cut my losses and take my lumps and put it on ebay with low minimum bid and forget about it.
