get an ion.
i used to own an impy & while they're reliable as hell they're also like house bricks...
people may hate ions because they've destroyed the market as someone said...but it's only because so many people have bought one, a starter 2nd hand tourney marker used to be £250 ish at lowest but now you can pick up a stock 2nd hand ion for £90 & upgrade it as you go until you've got something you can compete at a high level with.
Look at the WCU team's, -real high end markers, fast and very very light.
Otherwise, buy an angel- they're only cheap because they're au fait but there's nothing wrong with them, I bought an IR3 a coupla weeks ago & it's almost as fast as my speed, for how much? £95.
And guaranteed, that will not break when you dive, or get it wet in the rain
Peace,
whatever suits you, I recommend trying before you buy though.
