The ultrasonic cleaners are very exspensive but they are well worth it. I purchased my Crest 575HT from a police supply dealer for $1100.
http://www.policeproductscorp.com/ This unit is big enough for 2 handguns and came with all the accesories, cleaning agent and lube. I justify the cost of the unit with the amount of time I save. Cleaning 2 handguns the old way would take me anywhere from 1 to 1.5 hours. With the ultrasonic unit it takes me less than 20 minutes to clean 2 guns and they come out clean as new. It really only takes about 10 minutes of your time as you can do other things while the guns are being cleaned/lubed. My wife also uses it to clean her jewelery.
My cleaning goes like this:
1. takedown gun(s)
2. put in ultrasonic cleaner for 10 minutes
3. rinse gun(s) with tap water
4. ultrasonic lube gun(s) for 5 minutes in lube pan that fits on top of ultrasonic cleaner.
5. blow gun off with air compressor
6. put gun back together
No more sitting at the kitchen table for hours cleaning. :-)
Also you get what you pay for with ultrasonic cleaners. I wouldn't recommend the cheap units, they don't work as well because of the cheaper electronics.
