Sourcing Tallowwood

I've been keen on building this bench from Tallowwood ever since I began thinking about this project. What I didn't plan for was how difficult it would be to source in the sizes I need and a price that I can half afford. I nearly gave up trying to get hold of some quality Tallowwood and change the timber to some imported species but think I may have finally found some. Will have more to post in a month or so (hopefully with a picture of a big pile of Tallowwood in decent thicknesses).
