Preeeeetty sure summoning it does cost MP (Hence perpetual cost). There are gears out there in FFXI where it reduces the perpetual cost to the point where you can keep some avatar up in definitely... if you're lucky enough to obtain them.

Really. I played SMN quite a bit and I didn't find the perpetual cost to be an issue at all.
