which 521?

[unable to retrieve full-text content]

Ok. I can find the coil master 521 mini for £16.99. I don't like the look of it but the og, which I prefer, is £35! Is that too much for it now?
I can find pilotvape 521 for £27 but they are horrible colours.
My geekvape broke within an hour so I'm moving on...

Thanks
