Sporran. Dig around the forums here, and dig around your local area...try to find someone that builds them from real leather, on the premises. You should be able to find something like that for about (guessing here) 60-75 pounds, tho I'm not sure of the exchange rate...I'm thinking of a sporran I picked up for under 100USD, beautiful leather, two tassels, custom made, very durable. Should be plenty of things similar, where you are.

If you think that a sgian would be a nice accent, go for it...but it will likely be turned away from bars and sporting events. The sgian brew would be a better choice for both.

By the way, most sgians you'll find are going to be cheaply made in a third world country...or rather, the important part (the blade) will be. Find out where the blade, sheath, etc. are manufactured BEFORE you buy.
