I just made one of those myself for a fellow at work out of Wenge. The Rhodium plating was first rate, and he's quite happy with the pen. They have good weight to them, take a parker style refill (which I find to be higher quality than Cross of late), and due to the 3/8" tube have some thickness for holder.
Wenge is not a wood I plan to use again though, just no life in the pen. Under extreme light it's very pretty with small areas of brilliant yellow, red, and orange, but unless you are in an operating room, it's not bright enough to get that effect from.
Mike, did you find it difficult to get a shape to the pen that was not pretty darn straight? I've got amboyna burl in the lathe now and have been filling the voids from tear out in the grain reversals that I am trying to get a little more curve into the blank.
Had a nasty little skew catch at the very top when putting the very last cut to it, so I have a funky little head up there to work with. The kit is very specific on it's length with the supplied tube, just the trimming to size almost did in my Wenge one. Another mm and the insert would have not retracted into the nib.
