Bit of help needed folks,i broke my tube while moving machine yesterday,could have hit myself over it lol. Thing is been checking out ebay and noticed them at different prices and was wondering if anyone could help with a purchase before i buy anything. My machine was running a 50w and i noticed them at around £350 and some at £90 coming from Germany or so there shop was located. I noticed the difference in Beam diameter between the two sellers i was looking at. The more expansive tubes the beam diameter was at 2.2mm and the cheaper version was at 4.8mm, maybe someone could direct me . Im located in Ireland and even information on A uk shop or anything would be really appreciated. thanks Jamie
