I just checked that out. It's $25 but $41 for shipping damn!! I am desperate though so I might get it if my next flush is crap.
Heavensky what would you call an unsuccessful flush? I get a few (not many) stones out with every flush but my symptoms have not improved. It has been like this for 10 flushes. Do you think this means I have a batch of congestion blocking the way out?
