Whats a good Cat 40 tightening fixture, looking for something other than the one that came with my Haas. Something up to the $200 range if possible but I'm open to feed back.

Those are definitely nice, but not sure what you can do with them you can't do with one that has the top and bottom exposed... It is nice to index it 180 and have 'top' access to the pullstud, but not necessary IMO.
Forgot to ask OP what was wrong with the Haas supplied one? Yes, it is a little chicny and doesn't positively lock the toolholder in place, but been working with them for years and no issues....
These are nice as you can reach the pullstud and the set screw/collet/etc.

I haven't gotten my Haas yet to be completely honest but I've seen post on here about ditching it for something better. For the cost of one or two tool holders to hold it better, I'm ok with that.
We have a couple of these from Mari-Tool website.
One for our Brother and another for one of our Cat-40 mills.
Very happy with them.

I like these, called Tool Jaw. More costly, but you can find them used for under $200.

We had some trouble with these...We had a couple for our 30-taper holders and found that when tightening (or loosening...I can’t remember) collet chucks the holder would pop out. I was all, “noooo, we must be doing something wrong” but never figured it out.

Well.. surely my tiny corner of Hell ain't exactly "representative" of the INDUSTRY, but still.. I get by with that repurposed spindle stub because... only the newly-added TG-100 (3 holders is plenty, here) or the ER I have had for years even NEEDS a bench-mount tightening fixture. Most of my 40-taper is in Weldon-style side-locks or arbours for the horizontal. Classical fixture ain't necessarily useless, but neither is it critical.
Presuming you DO plan to run a lot of ER or TG - both MEANT to be precisely torqued to a spec, then whatever Frank Mari has in his MariTool line could be a sane choice.
Reason being if it is somehow sub-standard, yah make Frank aware of WHY yah think so, and he's one of the few vendors standing as will actively take notice, ask PM for corroborating input, and go about seeing to a better source or build a better one under his own roof.
Folk like that are scarce and valuable resources in a world where 99%-plus of ever' damn product on offer - food to foolishness - has passed through multiple layers of "don't-give-damn" and "not MY job" or "we've never had that happen before" hands yah can't even IDENTIFY with a Court Order, let alone get any support out of.
And yes, as happens I DO also "support my local SHERIFF". We got us a good'n.
The one I had at local college, when taking nice classes was junk, I've tried to find a picture to post up in my OP.
I'm not questioning Franks but being the new guy, I didn't know what the "norm" is.
I've been watching VA closely. I'm nervous what the future may hold.
You have to put the holder in so that it seats into the jaw when you turn the wrench. I bolt mine to the bench with the open side to the rear, away from the man using it. Then I put the collet nut to the left side to tighten it, or to the right to loosen it. That way you are always pushing down on the wrench which makes the job easier and safer and forces the holder into the tool jaw. Same for installing or removing a pull stud. I have them for 40, 45 and 50 taper, you can really horse on them with big wrenches without any danger of having the tool get away if you position it correctly.
