PUP, on the other hand, has to pay for every job ability the automaton learns. Stoneskin (Shock Absorber) costs 10K at the moment on our server, Flash (Flasbulb) and Convert (Mana Converter) are also around 10K and so on. Some of those attachments are quite easy to get, and they don't cost as much as the rarest ones.
You can, of course, play PUP without getting the best (and usually also the rarest and most expensive) attachments, just like you can play any other job without having the best gear available. But, I, as a player, usually want the best gear (well, not including the seriously too expensive stuff like relic weapons and so on), and I also want the best attachments for my automaton.
So yeah, I don't want to skip the opportunity to get a nice amount of MP back every three minutes for my automaton. I've wanted to get this attachment for a while now, but there has never been one in AH when I've checked. Well, today I checked AH again, and to my surprise, there were two of them! I was excited, hoping that because there were two, they would be cheaper than usual.

But, because people never undercut things I want to buy, I ended up paying 550,000 gil for it. No, that's not a typo. I did pay over half a million gil for an automaton attachment.
/sigh
After dying a little inside because I had just spent so much gil, I decided to go do a bit Besieged with my husband. Because Comedies automaton archery is now capped and I wanted to try my new attachment, I decided to go with the BLM frame. There was a double Besieged, and in the end of the second one, my automatons magic skill was 0.1 levels from the cap. So we went out to kill a few colibris and spiders and Comedie finally got the last 0.1 skillup!

Archery and magic done, only melee to go!
Oooo, and I almost forgot, I got something very nice for myself from Dynamis-San d'Oria yesterday:

Now I'm only missing the hat (which isn't really good for anything else than moving from a campaign battle to another or something like that) and the cape (which is pure hotness).
I also did a few synths today and got my Goldsmithing to level 45! That means I won't get skillups from Reraise earrings anymore, so I need to find another profitable synth for skilling up. I can still make money with them, though, so it doesn't matter that much.
