Replacement for Scottish Ale Yeast

[Anthony-Fucito]

Hello - I'm brewing a one gallon batch of Roasemary Scotch Ale, and the recipe calls for Scottish Ale yeast. Specifically they recommend Wyeast Edinburgh, but that costs $8 a vile... I'm trying to save money, is there any cheaper acceptable replacement for this type of yeast? I have half a packet of Nottingham tightly stored in my fridge that I'm thinking of using.
