Hey Jo-Jo
I am new to boarding as well and I like the Lecht (unless its swarming with kids who insist on tearing down the beginner slopes at frightening speeds!), been to Nevis once and used the dry ski slope but found it really difficult as there was bits of wire sticking up all over the place. Small dry ski slope at Loch Insh Watersports is good though!
I got my board (also girlie) from North 57 in Inverness, boots bindings and board package for £300. Seems to be about the average price, but you might want to try looking at Amazon.com (the US site) as they sell snowboards etc for VERY good prices, even including shipping to the UK it works out cheaper, so if you know what board you want then I would try that.
Might be heading up the 'Gorm on Sunday so I let you know how I get on up there as a fellow 'newbie' !
Determined not to fall on my backside with quite so much regularity this time
