Like Jeranhound said, you'd be pretty hard pressed to get a decent sniper for $200 or less that out-ranges the standard AEG.
If it's your first airsoft gun ever, I'd recommend some type of AEG. AEG's are pretty easy to use and you'll get into some decent action on the field. That said, the gearboxes can be a pain to take apart should they need fixing, only one of my AEGs has ever needed fixing. If you are interested in AEGs I'd recommend getting a JG G36C $125-ish new (because that was my first decent gun). I've still got my first G36 and it's been running like a champ for years. I've since moved on to other rifles/play styles, but the G36 was perfect to just get out and sling some plastic. I've seen tons of used ones for cheap. I've heard good things about JG for players who are just starting out. pick a gun model you like and see if JG makes one...
I've got a UTG (a re-brand of WELL if I'm not mistaken) L96 that I've tinkered with a TON and it's got some decent range/accuracy, but not much better than an AEG and I certainly wouldn't have been able to make the modifications I have made back when I first started playing airsoft. I wouldn't have know what I was changing or why. Oh, and back before I got my L96, I thought that these guys posting up that upgrades would cost "$300-600" were insane that they were probably talking about super-pro upgrades, but no, really, they know what they're talking about... Trust me... That said, in the future should you decide to get a sniper, I'd be with you on going the L96 route. I've put a lot of time into eliminate barrel wobble and the L96 has a great frame to aid that effort.
Post us a picture of whatever you get! It's always nice to see people's first guns! Take care!
