Hi mate,
Have you thought about attending one of the British Steel Guitar shows/meetups?
There's one in North Yorkshire at a place called Thornton Watlass.
A few guys attend this and I'm sure they'd be kind enough to let you have a go and give you some info regarding the foundations of playing and how to purchase an instrument.
Check out the events page on the forum. The next one is in February I believe as the Christmas, New Year break is on its way.
I think this would be the best route to give you the inspiration. In all honesty, pedal steel is a proper commitment, a lesson every couple of weeks on somebody else's guitar just isn't enough to take you forward. If you buy a good used pro model guitar you will break even if you want to sell so, the risk isn't as costly as me going out and buying a brand new Taiwanese Mandola and finding out that pedal steel is the only thing I'll play... True story

.
I'm over in Leeds and will hopefully be attending the Northern meetup someday but currently, my steel is in storage and has been for the last 2 months due to a house move taking too long.
Many thanks
Steven Hicken Jr.
