Wet float bearings

[rkvin21]

What is bad about using Wet float bearings(oil cooled journal bearings?)? I know that it is best to have ball bearing but to what point are they better. I have seen cheap t3/t4 turbos that have wet float bearings. Ik the saying you get what you pay for but it would be nice to get a turbo for less than $500. I did a search in google and came across a forum about using ebay turbos. Pretty much it has been a hit or miss with them and it is unclear as to what caused their turbo to fail to tell if it was only the turbo itself being poorly manufactured or not. I also came across a site that sells turbos and does turbo rebuilds http://www.blaastperformance.com/index.php.
