Brilliant, thanks for your help everyone! i shall get on it now! I think i will just go for the CM16 Raider L, save money on a scope i wont need
Also with regards the battery i have done some more research, am i right in thinking that an 8.4v NiMH battery will be suitable, i have seen that its useful for beginners but may not be as reliable as a LiPO battery. I think as im a beginner i'll stick with the NiMH battery and move on to one for advanced users later. However in the meanwhile is a 8.4v suitable or will i need to move up to a 9.6v battery (NiMH)? is it just rate of fire or is there more to it than that? i'm not bothered about losing rate of fire, i choose to conserve ammo and rarely go full auto on someone (unless they're not calling their hits)
Internally those two should be identical, so I'd just go with whatever you like the look of more as they're both good guns.
For batteries I'd go with 7.4v LIPO's, you'll need to do a bit of research beforehand to learn how to use them safely (they catch fire/explode if charged/discharged incorrectly), but they'll have a better performance then NiMH's.
One of the best places for batteries and chargers is http://componentshop.co.uk/
I use this charger: http://www.componentshop.co.uk/accucel-6-digital-charger.html
Will charge almost all types of battery including LIPO and LIFE, this version requires a 12v car battery to power it, the slightly more expensive version comes with a mains adapter.
