Basic maintenance is extremely easy. All you have to do is to remove the back panel (two hex screws) and then unscrew the whole firing assembly which will come out. You just inspect the o-rings on the firing can, bolt and bolt guide, wipe off the old grease, re-grease, re-assemble and you're done. The whole thing takes less than a minute. I do it every 2 cases shot or so. I only do a full disassembly (taking the board out, etc.) once a year when I do an extremely detailed clean-up. And even that is not that bad. You can also re-grease the reg piston every 6 months or so, which will add another minute to the maintenance cycle.
My SP-1 is now 6 years old and still works like a charm.
