You mean one ofhttp://www.juststoves.co.uk/?p=194 (these?<br />)
We have one and turf is a dog - the amount of ash is cruel.
The best fuel for it is wood - great heat and there's very little ash. Coal works well, but can leave a soot build up on the glass (fortunately there is an airwash system to remove the build up).
It cost us the guts of 2,000 since we had to get the hearth and marble surround replaced because there needs to be expansion cuts in them due to the heat. The lads installing it told us that in a new build you can vent off it to provide heat to other rooms
For us it replaced a gas fire that neither of us were particularly impressed with, and we both love a natural fire, so were very happy.
Edit: As for the wood being dry, I was chopping logs yesterday in the rain, and put them straight in and it was fine.
