In a different lifetime, I read a rave by Cliff R. about using one.
I then purchased one from an ebay vendor for about $600 (probably 20-25 years ago). It did a marvelous job of cleaning for about an hour and a half, and died.
From China, no warranty.
So I started researching USA brands, and bought one that, with the bells and whistles was closer to $6000. Best tool investment for the shop, other than a lathe, and milling machine, that I have ever made. The one I bought is still working well. 30 minutes will get the heat to 185 degrees F. It is large enough to hold any production carburetor I have ever seen before disassembly. It doesn't get as much use today, but 20 years ago 14 hour days, 6 days a week were common.
I didn't remember the name, so just checked; then checked the internet, and they are still in business.

Would guess in the last 25 years, prices have dropped.
Can highly recommend this manufacturer; and yes, they advertise made in the USA.
