alternative to cmc markets

Does anyone know which reputable CFD provider provides the least amount of margin required for spot silver? Preferably 1% or lower.

I know IG Markets require 1% for spot gold and 5% for spot silver already.

I had a brief look at GFT and they appear to be in that category 1% (but the website was updated in 2009 :S), so I'm not sure whether that's still valid. Plus, I've never heard of GFT. Are they reputable? Obviously I wouldn't want to go with companies that may go bust lol Had a brief read and it seems that some here have found GFT to be quite good.

I ask because CMC markets used to provide a 1% margin for both gold and silver commodity exposure, but they've now decided I've made too much off them, and are raising the margins to 3% spot gold and 5% spot silver, so I'm pretty pissed off and I want to switch. Plus, their interface is crap.

Any recommendations, please let me know.

Thanks.
