I would not recommend a MP7 as a first gun as it is an AEP (Auto Electric Pistol) or GBB (Gas Blow Back). AEP's tend to have very very limited upgrade potential, and GBB's are not a good first choice as they are high in maitenance work, and only can be used in warm weather.
P90's Do NOT get a CA SPORTLINE, Get a TM or a CA PROLINE. I had a TM, was a great gun but getting mags was hard and finding pouches and places to store them was a giant pain.
FN2000 only JLS, and G&G make it from what I know of.
JG aren't bad guns but they aren't great, expect to pay money at some point just to keep the gun working properly.
