So I ended up buying the Bennett lap steel. First impressions are good. The body is a solid block of mahogany with good clean carving, smooth simple lines, and a simple clear finish. Soundwise, it absolutely sings, gorgeous clear sound through my valve amp. The tone control has a very wide, almost wah like sweep, and sounds best set in the top half of its travel for vintage 1960's Gram Parsons and Neil Young soaring notes. This is a lot of guitar for the money :)
What tunings do you play yours in? i'm still tracking down a decent tutor book so have currently got it tuned to the E,C#,A,E,C#,A the chap in the music shop suggested.
Now I just have to resist replacing the pup with a Bare Knuckle...
