Being that horsepower is NOT my main concern, but rigidity IS, has Haas made their linear guide systems more rigid over the years? Are they STILL chatter boxes? Thanks in advance.

Compared too....... Under what cutting conditions..... Kinda hard to comment meaningfully without more info, are you trying to take a 1/2 depth cut or what?
I dont have much experience with other machines, but i can tell you what were doing on our ST10 now.
1.0 kyocera insert drill at 1.032 diameter, 500sfm, .003feed into 52100 takes 68% spindle load, but runs great *knock on wood*.
Parts off with iscar cutoff at 33% load, 300sfm .002feed.
Brand new machine with barfeed, doesnt shake, rattle or roll, holding size so far.
Long story short, no complaints from me about rigidity.
Sim,
I believe you will be pleasantly surprised with the ST over your SL. At least I was. And wish I could replace the 2 SL units I have with ST units.

All in all they lack rigidity and HP. Add an extra pass here and there, maybe back off the feed a little, especially on the larger end of the part spectrum and trying to push larger Indexable drills taxes the machines somewhat... but I have to say I have been pleased, guess that is why I have another one coming in this week. For me...it is all about just getting the job done in a reasonable amount of time and not so much about getting it done ASAP.
Really...thought that would be a big OSHA no no to have rotating anything sticking out. If using a Barfeed I guess it is safe, but if like me you Bar Pull that Spinning Sleeve is a possibility for a problem. I have the new Style Plastic Spindle liner on my SL-10 and it goes right up the the edge of sheetmetal with the nut on...but can slide the cover closed without a problem. Wonder if maybe the install is wrong.
JDJ, sorry for hi-jacking your thread.
