I'd second the recommendation of Sean's pipes - I have some of his starter G's myself. You could also look for Dom Allan in Somerset

My top tip is that you should try to find a piper near you before you buy a set - the BagSoc should be able to help you out. If you're on Facebook you could look for the relevant page, or go to the website and contact Ian Clabburn, who deals with general inquiries

And yes, the Blowout is well worth attending

Good luck!
