Grace 714 tonearm....any experience?

I am looking to find if anybody has any direct experience with the old Grace 714 tonearm. That is the one with the teak arm wand. My recollection is that it was pretty pricey in its day and got pretty good reviews; maybe Grace just had a good advertising budget. In any event, if this is a good arm AND suitable for higher mass/low compliance cartridges I may make an offer.

On the other hand if building arms out of hardwoods was the "thing" to do I would assume that more makers would use that as a material; great minds and all that rot.
