I have an etna - stainless steel, bought off fleabay some four years ago for £20.00 including postage still going strong apart from
1. broke the little metal loop on the lid used for opening it (me being both rough and clumsy when it was really gummeb up with tar)
2. Bellows on the way out last season maybe partly due to the fact I keep forgetting it up near the hives for days on end in the rain.
So apart from replacing the bellows with one from the sales (£5.00) it's still going strong and looks a lot more robust than my spare which I bought in the sales last year for £12.00.
And I like the inner basket insert rather than the little grid you get in empires
Maybe the etna is a little less 'pointable' than the empire but otherwise no difference
