The NP203 isn't a bad case. It is stronger than the 208 but not as strong as the 205. They are chain driven and heavy. Several companies make part time kits for them but if you do that, you have to run them in 4wd once in a while because the chain is what slings the oil for lubrication. They are a strong case. The 203 is used in conjunction with the 205 to make a double for rock crawlers, etc.

Unless you are going to be doing some extreme 4x4ing, you'll probably be ok with a 208. I think you can buy adapters for the 205 to mate up to the 700R4 but they are kind of $$$.
