The above is Gen 2. A few color combos available. Theres a gen 1 as well that's cheaper but less color choices.

The Best V8 Stories One Small Block at Time
I use the $25 ebay ones with the two 10AN fittings and a filter on top, but they have no baffling other than a small screen, so I put the foam inserts in them.

I used these ~$25 ones with the screw on top/bottom so you can open them up. The welded versions on ebay are garbage and yet are the same price.
The only problem is that all they have inside for any kind of baffle fine mesh screen. That would at least be OK if it was above the fittings, but it is in between them.
My go-to is usually steel wool pads. I'll use a higher grit in the top, like a grade 4, and in the bottom usually something a little finer like a grade 1.
Stretch them out to fit their spots. The grade 1 will stretch a lot before it thins out too much.
I've also used these in the past but they aren't as easy to find, but still only $5 or so. Tetra pond filters. You can get them in almost any size and just drop them right in.

I have one sitting on the shelf in my garage I’m not gunna use. You get what you pay for (cheap junk).
I bought the filter from Amazon for like $8 shipped or something.
I have $35 in the catch can, $45 in a 10AN braided hose kit with fittings from ebay, and $20 in a pair of 10 AN oil cap replacement things since I run 2 passenger side valve covers.
$100 in the whole catch can setup. I couldn't bring myself to spend any more than that lol.
