Anyone used 'Silver Sequence'?

I tried it only out of curiosity at the time when it was just introduced 
and one could get a free sample. I think that it has a certain, although 
limited, use. It is based on a mega-version of cycle sequencing and 
indeed generates about 10-fold more sequencing products, than a typical 
radioactive experiment. I ran a T7 sequencing sequencing experiment on 
the same gel and could barely see the bands... However, the sequencing
kit and the staining module can be used separately for other purposes, 
so if you are limited in the use of radioactivity, you have a viable 
alternative, but will have to spend somewhat more on DNA purification.
On the other hand, I had great success using this kit with DIG primers ( 
Promega sells the sequencing kit and staining kit separately ) and 
associated chemistry of membrane staining. This latter one can compete 
with radioactive sequencing in versatility and sensitivity, but you will 
have to invest in a drum roller oven and a DBE apparatus to get 
comparable results.. ( quite some money but still much less than a 
fluorescent sequencer ).
Hope this helps,
