I need to set my digi up as per rubjonny's faq. Are the gas testers that halfords sell any good? They claim to be accurate to 0.5% but I want to make sure it's the right tool for the job before forking out 100! http://www.halfords.com/webapp/wcs/..._productId_188065_langId_-1_categoryId_165557
Thats the one i brought to set up my digi done the job ok. Try and get a Halfords trade card. I got one and it only costs 40 on trade.
