TeleK,
In fact, you can get a reasonable starter lap steel for not too much money which is good enough to learn on. Proper lap steel playing is so diferent from normal guitar or slide playing (especially in the right hand technique with the finger/thumb picks) that you may be better off getting a cheaper instrument to start with and upgrading when you know you have taken to the instrument.
Fender d0 a good little lap steel (at £300 in the UK). However, if that is too much you could try one of the really cheap Artisan models. You can pick these up for £50 or less in the UK. That's is how I started. The pickups are awful, the jack socket is in the wrong place and the nut is a complete waste of time. What's more, the strings it comes with are entirely wrong. However, with a bit of work you can turn this little plank of wood into a reasonable lap steel, which is what I learned to play on. I have now traded up and got myself a starter model pedal steel.
I learned to play lap steel in C6/A7 (with the lowest string raised to C#). It was interesting to learn to do it this way because I ended up learning a whole new style of playing, whereas if I learned in open E I would have been lazy and ended up playing like I play slide guitar. Do yourself a favour and learn in either C6 or A6 - it'll be worth it in the long run.
I'm learning the pedal steel in E9 tuning. I have to say I'm a little surprised by Ron's set-up with only two raises. I guess he raises the 3rd by a semi-tone and the 5th by a tone. That seems pretty limiting to me but he does a reasonable job all things considered!
Anyway, try this link for more info on the lap steel guitar...
