That'd be great, but once again, if ya don't know how to do it..
cost of materials + cost of someone to build it for you + cost of shipping it to you
more then likely cost WAY more then
cost of a cheap android tablet (just found a decent 9" tablet on NCIX for $109.00) & it qualifies for free shipping, so thats nice. + a less then $20.00 app, will allow even your budget airsofter to be able to have a great game style
