I think TC2000 is best overall deal for end of day scanning. I don't think you need to get fancy with the PCF's either, you can do a lot with the built in stuff.
What built in PCF's do you think are the most valuable? I think the tool is pretty good, but I have been reviewing the Worden notes of a few tech stocks during the debacle, particularly CSCO. Man, did he blow it - he was pretty much riding the "slope of hope", although an astute use of the tool probably would have been useful.
If you have programming skills, you can use the development kit that comes with TC2000 to interface with Visual Basic and write scans and a whole lot more. Ed
