I also have the ability as seen in my website to take videos of the markers in operation, or flag those that don't work, and have a uk mobile phone, so you can ring or text me - i shall only provide this phone # for those who have paid me, as i dont want to be phone flamed!
I only have co2 at the moment, but hope to get an hpa tank for my PT Extreme, and when i have done this for long enough will buy another hpa tank (low pressure), i will also no doubt be able to change o-rings, and flag defective/worn parts of the marker, and alert both traders as to a possible dodgy trade - nobody wants to loose ages of savings, let's be honest, and excuse the shoddy website - i don't do computers! (although i will check my email constantly when somebody is using the service
)
Oh, and i'm only making money out of it mikey, as i will build up a collection of marker parts and 2 air tanks to film and try and fix the markers, as well as me taking mill classes, (which cost money!) so i can halfblock and mill markers (cockers mostly
)
