Hi there. First you might want to read this somewhat recent thread:

My detailed review of the 2479 (large dutchwest non-cat everburn stove) is here:

Without a doubt the everburn stoves have had negative feedback on the forums. Did you buy it in 2008? If so the warranty will be honored. ALSO it is worth noting that according to some they improved and redesigned the rear refractory shoe piece, changing the angles and bore diameter of the holes which supposedly makes the stove work better. This has yet to be confirmed by anyone on the forums, so maybe you can be the first. If you did NOT get the improved design, personally I would want to follow up with the dealer I bought from to see if they can replace that part.
It sounds like you have a good setup with a nice long straight interior chimney. So one big question is how is your wood? Its basically too late to start seasoning wood right now, so hopefully yours has already been split and out drying all Summer. It is going to take some time to get used to this stove, but you can learn from others that own one and you will get better results with time. I generally tell people the everburn stoves are not worth the hassle, and if you can exchange it before you burn in it, I'd consider getting a stove with better customer satisfaction. But if you are determined to stick with this stove or you don't have much choice, I do think its possible to get good results from it. I have been heating 24/7 with it for the last two heating seasons.
As for cast iron vs. steel - this is a long running debate and something that has been discussed many times on these forums. When all is said and done I think its a toss up, they both have strengths and weaknesses. Cast iron stoves tend to have nice curves and grooves all over the place, this design not only makes them better looking stoves, but it helps them radiate heat better than a typical steel stove. The vermont castings cast iron stoves are also now completely "bolt together" (no cement) which makes it possible to somewhat easily rebuild them and/or replace a single part without scraping the whole stove. A steel stove might be more durable as a mostly single welded together unit (they can warp or crack though just like a cast iron stove). As was mentioned, the quality of the casting (foundry it came from) plays a major role. The VC foundry is the best, so if cast iron stoves have a bad reputation it could be due to sub-standard product coming mostly from Asia. But honestly I am not aware of cast iron really having a bad reputation.
