I just finished the RG Zeta a few weeks ago after several years of on and off poking at it. It looks a bit off, I don't think I collapsed the hip section properly. But at this point I don't want to touch it. Every joint feels like it's either going to flop, or doesn't want to move. I have a set of waterslides for it, but I don't know if I have the patience.

Luckily, I have avoided all the infamous kits so far, so I haven't had any truly bad build experiences. My least favorite would have to be the HG Freedom + Meteor unit. It's not bad, but really shows its age. The Meteor unit is mostly just sections of two large hollow pieces of plastic sandwiched together, and would require a lot of masking and painting for color correction. I didn't even bother building the Freedom that came with it since it's also the old one, and placed my HG Rising Freedom in it instead.
