We are looking at woodburning stoves, around max 5kw would suffice.

The guy who is going to fit it likes Esse and I quite like this,

Cheapest I can see it for is £670 quid.

I don't want to save money buying something cheap and naff but don't want
to spend more than necessary.

So general opinions would be appreciated on stoves and prices.
