I'm not planning on buying either a Waki or a Tank Buster; unfortunately, I've spent the money that I "saved" by sitting those out multiple times now, mainly on the secondary market. I was tempted by the Tank Buster, but it seems to be in the same class as the Satin Jack. However, I like the ETS SJ better and already have a few, so they make the TB superfluous for me. Also, I really liked having a few custom options (i.e. the Scrapper 5 release), but as many as are available on the Tank Buster feels gimmicky.
