I hate spending time cleaning my guns and have seen ultrasonic systems for sale. Of course they're very expensive. Have any of you used one and was it worth the cost.

Also, are there any other options? I remember working in a garage where we had a parts cleaning system that used solvent that cycled through a filter. I've often thought a small version of this simple system would be good for gun parts.

What say ye?
