Depends on if you plan on doing more. I personally when i get back to playing EVE, and being in highsec again, will drop a POS in a sec 6 system where i will be mining or basing out of. There are other useful things to put up in a POS, like Labs if you plan on doing manufacturing & Research.

If you plan on doing research like i assume you will want then, setup the POS when you are ready to do that. POS fuel has gotten very very expensive.

If you have no need for any POS Modules there is really no need to setup a POS in highsec, when you talk about 0.0 or WH space then that response changes.
