Delta Millworks in Texas has a really great selection. I'm quite partial to their gator texture.

Yes, it's more expensive due to the added labor costs to control burn the wood, but it's such a unique look and has numerous benefits (termites and pests don't like eating burnt wood, burnt wood is harder to catch fire again, etc), but the main benefit is the unique aesthetic. It truly is a special material. Reach out to Delta and ask for some samples!

I was looking into it here inAustralia and was told it definitely needs to be re oiled every 2-3 years and will fade from the sun - Iam going timber composite cladding for the no fuss maintenance

There was an episode of Grand Designs NZ where it was used and the owners did it themselves. It was a really interesting build and I would recommend you have a look if you're interested in this finish. From memory, the owner was a builder and it was a pretty high end project.
