Ultrasonic Cleaner for Firearms

Does anyone have experience with using an ultrasonic cleaner for firearms?
I watched a video using an Infante Ultrasonic Cleaner for a MAC 10 and was impressed how easy, fast, and clean it was.
I am thinking of putting an original Ingram Powder Springs MAC 10 .45 up for sale and field stripped it for pictures.
I thought a quick bath and lube would help.
If you have a cleaner, would you be willing to run it through?
Of course, I would pay or trade ammo, etc.

I have one. It works, but isn't a silver bullet for all problems. To be fair, my in an inexpensive small chinese unit rebranded by Lyman. It excels with suppressors when used with CLR. For generic gun parts (a bcg for example) it's not better or faster than a toothbrush with solvent and then a spray of brake cleaner.

I'd very much like to have one large enough for a complete upper, or at least large enough to submerge the entire upper casting, even if the barrel had to hang out.

The Infante Ultrasonic Cleaner is a bit pricey for someone that isn't doing this for a living.
I looked at the 30L sized ones on Ebay, Amazon, and on-line.
I then realized 30L is equivalent to about 8 gallons.
I resorted to the old method of hand cleaning with brushes and solvent, wiping down, light lube.
I am not sure it was as effective as the Ultrasonic Cleaner, but it makes the operation smoother.
