just to run 2 accounts at the same time with some ease (ie: one keyboard), It would be nice to not have to pay an upwards of $50.
your math is a bit wonky. if you use keyclone, you can run both accounts on a single machine. as such, you only need 1 keyclone... $10

if you have multiple machines, then you'd need a keyclone per machine... but with only 2 accounts, you'd max out at 2 machines. (tough to run 2 accounts on 4 machines)

and AHK is free... you'll just have to work at it to get it going.

as for being nervous about software.. i can understand that. i only ever load software i receive from reputable sources with some level of accountability (like i could call them). if i could not get in touch with the people, then i'm pretty nervous.

and if keyclone was doing anything like that, i'm sure you'd hear about it all over this forum... there are quite a number of hardcore geek types here watching everything.

and need i mention, ALL viruses are free...
