I don't like my Summit Press. I LOVE it!
At last a press that doesn't have a bunch of knee-knocking mechanism below the bench top.
On primer collection, the little cup they provide is too small for a serious loader. I cut the bottom out of mine and attached a piece of soft vinyl tubing to it. The tubing then directs the spent primers into a large coffee can. If I bump the tube with a knee it doesn't leave black/blue bruises.
I too found an issue with some side-play when I received mine. The top casting was a little loose on the column as well. I wrapped the top of the column with a strip of .001" shim stock, reinstalled the top casting and now it doesn't work the top bolts loose.
To adjust out all extraneous movement of the die holder casting I move the operating lever to a horizontal position, tighten the top screw on the rear until it keeps the handle from falling on it's own, then loosening ONLY ENOUGH to let the handle start to fall on it's own then tighten the lock nut. I repeat on the lower screw. this results in the casting being held firmly against the front of the column, riding on a thin film of grease, and no side/side or other deflection of he die holder.
For grease I picked up some grease from my local bicycle shop that is white and supposedly laden with PTFE. The white grease doesn't stain as badly as all the other lube's available and after 1,000 rounds or so, the column looks like it's chrome plated.
The result on my press, using a Forster BR sizing die, is cases that with darn few exceptions measure .0005" or less runout measured at the center of the necks.
I also ordered mine with the short handle which is great for seating bullets.
Only complaint now is that someone else was able to buy one for almost $100 less than what I had to pay
