Only ones I’ve played are:
Aderdour – loved this. Great views and a parkland.
Eden Course – about as close to the Old Course as you can get whilst spending <£100. Decent course in its own right.
Crail Balcomie – might be a bit expensive but a great old course with lovely views and very welcoming.
Anstruther – quirky but fun 9-holer.
Would recommend all.
