Now, I know you'll probably hear this from more than just me but, you really are just better off waiting, especially for a P90. This is not even a chinasoft vs. TM debate as there are no clones of the TM P90, so it really is crapsoft or bust. The closest thing would be the JLS FN2000, it is based on the P90 (the Real steel FN2000 that is.) but uses M series mags instead. But that would not be that much cheaper than a TM P90 anyway (save for the mags.)
Edit; Frick why must people post while I am busy typing.
