I recently got my hands on one of the Kernow models s100 made by Bachmann Making it my second Kernow exclusive after one of their Dapol sentinels I bought I would highly recommend both of these engines. Both are at a decent weight, the s100 runs at the same speed as a Hornby austerity 0-6-0st and is almost silent, However the sentinel is a bit noisy but still a very good smooth runner.

here is a quick link to see the sentinel running so you have an idea of the speed and sound. non of it has been edited so this is exactly how it runs.
