Flashcut vs desknc for windows & Deskam

Hey group experts, I e-mailed this question to flashcut but never
got an answer. I am in the design/parts requisition stage of building
a gantry router/plasma table. In my research I have found that both
flashcut and desknc windows use a signal generator to get around the
windows clock problem (whatever that is). I downloaded versions of
each and to this newbie they seem an awful lot alike. The flashcut
seems to be a bit simpler for initial set up of the machine but for
half the price I don't mind spending a bit more time on set up. With
nc you have to purchase the signal generator for 200 to 250 and the
software is free.(with flashcut,you purchase both as a package). You
do need to add a cam program such as deskam or another. Also,I
hav'nt seen the deskam on the database yet. I read somewhere that
desknc for windows is "kinda clunky" whatever that means. I asked the
flashcut people to "sell" me on the benefit of the extra expense. As
I said, there was no response. Could it be that the benefit is either
small or nonexistant? Any help would be appreciated.
Thanks, Dale
