I think that if you, as GM, are willing to assist in the set up of the powers (I believe you mentioned this is a new player, right?) and that the powers are only changeable "at lab" (between sessions) so as not to slow down playing time, a VPP is a workable solution.
Is he going to be changing/creating new weapons as he goes? If so, then yes, definitely a VPP. If he is just planning on using the same weapons all the way along, then I think a MP would better represent this.
OR,
If you, as GM, allow multiple PF's, then have him build a standard arsenal as a MP and then have a small VPP gadget pool to make "special" equipment he may need. For example: If the party knows they'll be facing the Sinister Dr. Simian and his battalion of Ice Monkeys, then before they leave the base, he may want to stop by his lab to create "Thermal Insulation" for his uniform, that gives him, say, 10 ED vs. Cold damage, or, whatever.
