Anything from the F90 line is a 10/10 if you just feel like burning money. They cost too much for how small they are but they really are very good. Otherwise I can just list off some arguably flawless kits that don't require selling some organs.

The sinanju has the same type of bead assembly as the zaku heat pipes but it both includes spares and has an assembly which is a lot less fiddly to put together. It also needs a bit of paint to truly look great but the stickers it comes with are serviceable for a snap built model. You lose some of the depth from the sculpt using them but they're fine.
Every one of those models will look good snapbuilt or if you paint them. None of them need any color correction beyond using waterslide decals that they come with in the case of the F90 line or the red sinanjus stickers.
Pic related, some sinanjus I did.
