I was in the same position, wondering which way to go, but I opted for Koda.
Its a bit more expensive than the pellet version, but just for ease of use its fantastic. I did consider the multi-fuel version, but realistically I would have brought the gas attachment at extra cost, and would of used gas for the majority of the time.
The only thing that concerned me, was if pizza tasted better from a wood fired oven, but after reading lots of opinions, I don't believe it makes any difference. A pizza doesn't have enough time to absorb any of the flavour from a wood fired oven, due to the exceptionally quick cooking times.
