Any experience with the press in oil return fitting from either yoshifab or STS (or both!). Pros/cons? Thanks!

I can only speak about the Yosifab fitting. Its awesome!

My install went so easy I am going to do this on my newest project.

Yoshi don't mention this because people don't know how to go about things with out hurting themselves I guess, but if you warm the engine first for just a short time and then allow the exhaust to cool enough to where you can work on the car , having a warm block even makes the install easier. I put the fitting in the freezer ran the car for a few minutes, removed the old and cleaned the surface area as instructions said to. Then got my fitting out of the freezer , wiped away the moisture and frost , cleaned both surfaces areas with brake clean , put the lock tite on my fitting and barley had to even tap it in, but I had my mallet and was ready for it. I allowed my car to sit for a whole day after and 2500 miles later no leaks. So I am happy with Yosifabs fitting.
 
I made an adapter that's very similar to the STS one about 6 years ago, before they were even making them. It hasn't leaked at all, and it's so easy to install... it just slides in and seals with o-rings. It's been in and out a few times, and never a leak.
The STS one is stainless, uses viton o-rings, has a wrench flat machined in for loosening the hose... and it's very well priced.
 
I wasn't aware sts made a fitting, looks nice though.

I just finished installing the yoshifab fitting. Just a heads up if you have a 7/9 series, you'll need a 45 degree fitting at the block end of the hose to clear the oil filter.

I second that..you can have a straight fitting attached, but its tight. like rubbing on the filter tight. mine is currently straight, but 45 would of been better
