I'd wait to see what the internals are like. The EX2 was garbage out of the box all around and difficult to mod.
You'd honestly be better off just getting a Madcatz FightStick at that price. Better case, likely easier to swap parts out. Though, I don't know what kind of deals are to be had on these in the UK. Check Amazon.
EDIT: Found a thread about these over on Shoryuken. Particularly,
this post, which shows a shot of the internals, would make me stay away from this stick. I will never buy another stick with buttons soldered straight onto the PCB. If the PCB goes out, or a button fails, it's a pain in the ass making your stick a non-paperweight.
Though, if you scroll down on that page to posts #43 and #46, reviews of the stick seem favorable.
I guess if you're going for a budget stick that looks good, this might be for you. I won't skimp on an arcade stick ever again though. You get what you pay for when it comes to this type of peripheral. You end up spending two to three times as much in the end because that cheap stick leaves you wanting something better.
