Robbo,
I'm currently with Tayside at Fife (Glenrothes) booking requires about a week in advance due to popularity, but you can book several slots at the time, good idea cos weather has a say in things, I usually book about 4-6 in advance then keep a check on when your last one will be & book some more a week or so before your last one, you only pay as you fly them unless you are on "account".
Books are about <£20 each, 7 off total buy as you need them, start with Air Law you need to pass that exam before they will send you solo. Get the "Confuser" invaluable ~£20. Buy nav kit as you need it, you won't need it in the circuit to start with. Scotland chart 500mil £13, good to look at & learn about early. £200 total is probably close but less painful if you buy as required. Get a decent pair of sunglasses, take-off & landings at Dundee 28 are into sun in the afternoon.
Anything else just ask.
Trevor.
