£150-£200....buy another g36 and keep a hicap in it!
Sorry you are worried you only have 1 battery and 2 mags, and want to spend shed loads on a pistol. Surely if you are worried you buy more mags and another battery for £40.
What you want to say is what pistol for £150-200
If you only have 1 AEG, I would say spend the money on a backup weapon, couple of mags and another battery. So when your main breaks, which it will, you have a spare AEG to go play with.
