There are already quite a few cheap vertions of the cylinders available that are 'close enough'. And there is nothing wrong with those at all. I am one of 'the nuts' that is willing to pay a higher price to get as close to screen accurate as I can. I've paid £350 for a Sterling, £100 for a scope and £100 for a counter so I'm not going to use a 'good enough' set of cylinders on my build. I think Andy will be catering to the hardcore detail nuts such as myself.
