AIM/chassis tech spindles

[Cautrell05]

I am looking for drop spindles for my s10/47 project. Specifically the 92 through 96 Impala spindles. The belltech spindles are about 410 bucks no matter where you look. The chassis Tech ones are about 250. Now I know if you Google it there's lots of threads where guys say they are junk and had problems with them. Almost all of the threads complaining about them are from 10 years or more ago. A lot of threats they just say their junk but I haven't heard any specifics as to what exactly is junk on them. I can't help but think if they had problems with them 10 years ago that they would have it fixed by now. Any recent input on them? Thanks
