I ended up at SLH. Found a board that was reasonably clear - at least I can use about half of it.
Had to be maple - I'm building an art deco style hall table and have a lovely piece of tiger maple for the top so I want to match it. The unit will have dark black walnut legs and three glass panel inserts for the top sitting on padauk.
Got the top machined and assembled today. Cut and planed the walnut to size for the legs (not as dark as I'd like but a bit of extra stain will do the job). Got the SLH wood cut and planed so it'll look OK. Had to change the design slightly - will put a very small overhang (1/32") on the top to the SLH sides as a perfect butt wouldn't look so good.
Going away for a couple of weeks (work

) so can't do any more until mid Sept.
