Best Spreadbet Provider for FX?

I am based in the UK and trading FX using spreadbets looks like a zero tax route. The majority of the spreadbet companies do not offer overnight rollover without taking you out of the position and re-entering, the cost is more applied spread which I would obviosly wish to avoid. FXCM are the exception but there are other major issues with them which are well rehearsed elsewhere on this forum.

Does anyone have experience of a stable, reliable spreadbet FX platform they have used??

I have experience of IG and City index and both seem ok,
I have personally traded with IG back when i lived in the UK and City's offering was always pretty close.
I think to have the spreadbet classed as a bet the positions have to be closed and re entered so that could be why it happens.
