    Attached is a circuit I've had repeated success with.

    I suggested the 2N7000 because of its availability, general utility and very low cost (about 0.11 USD in single quantities). It's been around a long time. Both the MTP3055V and MTP3055VL are also readily available and moderately priced (about 1.16 USD in single quantities).

    I have to echo Paul's questions:

    What kind of load are you driving?
    What current capacity do you actually need?
    How often will you be switching?

    We could probably be a lot more helpful if we knew these things!

    "Easy to use" is easy to say.
