Most stoves originating from the far east seem to be left handed, the notable exception being Danish manufacturer Morso.

Ekol	The Ekol Clairty range are quality affordable burners. The range is all left handed. I retail Ekol stoves
FDC	I'm fast becoming convinced there is not much on the market that is better value than FDC freestanding and inset stoves. Steel fabrication with cast doors, they don't permit web based advertising of their prices but they are not dissimilar to Firefox. DEFRA approved, high efficiencies (i.e. over 80%). I retail FDC stoves
Morso	Well thought of Danish manufacturer.  www.morso.co.uk
Sunrain	Chinese made budget stoves of respectable quality. Sold in the UK under a number of other brand names including Fireglow and Firefly? www.sunrainfireplaces.com
