Whatever you do with the PS pump, I'd still ditch the smog pump for a pulley.
Jim C (tlcperformance.com) sells a good one. If the smog pump is not in your way now it will be before you know it. Don't throw it away though - somebody out there will need it.
Your own “medium“ option is actually the best. As OSS pointed out - new OEM, with reservoir, is still available from Toyota and will last you another good long while. I got mine from Camelback Toyota online years back - I think they’re more reliable and just as competitive as Parts Deal.
