Been toying with this idea for ages, there is a good offer on the one I have my eye on
Ultra 7000 at Maplin £25. It has been seen as low as £20 on Aldi special. I have heard that these really get all the oil out of your chain so you need to make sure you get it oiled again properly and yes you need to turn the chain over once so it's not faff free.

There was a good discussion on this a while back but I can't seem to find it, Mad Pierre was the expert as I recall.
I bought one of them and dropped a chain in with just hot water, did two 5 min cycles it was still dirty add some washing up liquid and gave it another 2 x 5 min cycles it was still dirty

.
i took another chain to work and gave it a blast with a 9 bar steam lance and it was spotless which is was i was expecting from the ultrasonic II'meaner.
Im going to try the cleaner degrease degreaser in and see how that goes.
