For the love of god, don't get a sniper rifle for you're first gun! I did the same thing, I got the VSR-10 and It was the biggest mistake I have ever made. If I could go back in time and buy an AEG, I would, but its too late now. A sniper rifle seams great, but has no range at all compared to a real sniper rifle. Also, the ammount of money you need to spend just to make the sniper rifle half decient would be a waist.
Take my word for it, although it isn't the highest in power, buy an AEG first.

Today's wounds are tomorrows scars
Tomorrows scars are your life's war cry...
