Best fixed odds site?

All I see is spread betting.. I'm using ladbrokes but apparently they aren't a good choice long-term due to their bookie status (barring profitable accounts etc).

So what's the site to go to? I don't want spread betting, I want fixed financial odds for short and long markets, whether say gold will fall to a value or not etc

thanks

I think still BetOnMarkets is the best, though it's a pale shadow of its own glorious past.
