I bought a Samsung 850 Evo 500gb drive from PC world for about £125 (same price as anywhere else and picked it up same day).
Installed it in about 20 minutes myself - it's dead easy.
The next day on 'Amazon Prime Day' they had a 750gb Crucial drive for £100 so I got one of those as well. £20 for the Optical drive bay thing, another 30 minutes work and I'm SSD to the MAX.
