If you can afford it, I strongly recommend cybereyes with the smartlink feature for 5e.  It'll allow you to not only obviate the need for goggles and all such but you'll be able to get the +2 for wireless even while jacked in.<br/><br/>Raising a skill group from 1 to 2 is only 10 karma, not 15.  It's 5 * new rating.  Yes, I realize that the chart is really dumb, but that's used for when you start a skill from zero.  Normal skills are 2 * new rating, so you only need to spend 6 karma to raise Pistols to 2 if it started at zero.
