I got mine from Amazon. £440 inc. delivery, I've no idea if that's cheap or expensive, but seemed about average for this part of the world. Ordered it today, I'll get it Monday. Money wasn't so much the issue... if I get along with it! If it's not worth it at £440, it wouldn't have been worth it at £150. As for the rig, I'm probably going to build my own, I can get a seat from a Scooby or an MR2 for the price of a pint of beer, and I'll construct the frame to suit from mild steel box section. Space isn't the issue, but (unlike with the wheel) I'm not about to go spending a lot of money for something that isn't worth it - so long as it's sturdy, and fits me, I'm happy. Honestly I could spend £500 on a ready made rig, but, I'm expecting to be able to make one for not much more than a 10th of that.
