Long Briefing - usually I would agree with a sensible comment like "pay no money up front", but Redhill Aviation offer a healthy discount if you pay for your 45 hours in either one or two bursts (saves about £600 - 700, I think), so Sky Leisure may well offer the same deal.
Of course, if you don't trust 'em, don't pay though! <img src="smile.gif" border="0">
Enjoy the flying, Miss - Shoreham's a nice place to do it from!
