yeah yeah, as your first gun buy a sniper and spend 500 quid on it. no. do that later.
Yes TM's are very nice, I have one myself, but it wouldn't be top notch to have the most amount of fun as I could with it. As it's manufactured in japan (I think, somewhere over in East Asia) they have an FPS limit of airsoft guns, it's like 300 FPS. You may have heard of people who own snipers being like "oh ye I have 450 FPS sniper" well yes,this is true, even if they have a TM sniper, what they did was upgrade the FPS, either through a higher power spring OR mancraft SDiK (I'd say these are the main two) but I think there are others.
The problem is, people want to be a l33t sniper with headshots and all, and they watch people like Novritsch, and see him get many kills per game, so you buy a sniper and try be like him, and most likely, you spend money on upgrading, and think "well I'm still crap, I give up" and this deflates you, after you've spent lots of money and have no gun to have fun with. Chances are you could quit airsoft (could, don't though, it's awesome)
though you could go sniper, and have some fun, but it costs a lot, I'd recommend spending the best part of £150 and get your self a G&G CM, which will have you dandy, then after a while, of enjoying airsofting, go into the sniper route.
But if you do end up going sniper route, PM me and I'll tell you how much I spend/what I did/what route I took etc. even if you do go for an AEG PM me anyway and I can let you know about sniping.
If you really want just get a TM VSR/ or JG BAR10 (vsr clone) and then look about on the forums and you'll find what other people did and what advice they got.
Good luck my friend, feel free to PM me if needed.
