After buying a clone GBA (which was disappointing), I have decided I am going to buy an EZ flash IV (the new, black 2015 version). My intention is to play GBA rims from this on my SP.

Considering I live in the UK, which website (preferably UK) is most reputable for me to buy my EZ from? I've heard satires online of people ordering such cards and the website going offline the next day, and I really don't wanna be on of those :/
