I still build some of my rust buckets OOTB. I may alter or modify kit parts and of course leave some parts off entirely. It's all in what you do with what is given...no need for all the added AM parts if you choose not to. Now a days the kits like Dragon are so detailed and give you so, sometimes too many, many parts that you can build a really nice model OOTB.

Most of my add-ons are scratchbuilt with maybe a bit of PE. My wallet isn't deep enough to buy all the goodies.
