Well, I've taken the plunge and ordered the rule book but I have a few questions on models.

Are there any good ideas out there for conversions for orks? My plan so far is to order a couple ork fighta-bomba blisters from the epic range and convert them to fightas to deal with imperial thunderbolts (at least until I'm sure I like it, forgeworld has some great models) but I was wondering about scratch builds as well. Any tips or pics of orks in action?
