Mods? Which one

[D3VsT3R]

I know the answer to this question, and its a messiah!! but not only can i not afford one, but i am not prepared to solder the forty odd wires it needs. So out of all the other mods, which one is best. I have already moded a NEOKey USB job, but am not that impressed with that. what are the no solder type R mods like as compared to a NEO 2.2. Or what about the Neo 4. I know nothing about any of these. What are they like.
