I have been looking into ultrasonic scalers. These can do a marvellous
job of removing encrustations from shells, especially spiny ones. They
can also be used for some fossils.
The Chinese are making quite a few, and prices are WAY below US or
European-made units.
For instance, Yunsheng Medical Instrument Co Ltd's Model YS-CS-A for
special price of $156. Contact: Yuki Zhang <[log in to unmask]>

Nanjing Foinoe Equipment Co Ltd sells its Model-K for $140.00US, but
for that price the minimum number of sets is 5. Tips are $2.00 each,
minimum 10 (that's gotta be cheap!). Contact: Export Manager Bob Jiang

Zealand as Intop DDUSC 02 as well! I haven't bothered to find out the
price... probably 3x the above for the same unit.
