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.
