Hi Preston,
I think the Olympus DS-330 is a very popular model. Make sure the one you get has a docking station so that you can upload the dictation into the computer.
As far as encryptors, I use one because I have a newbie who e-mails her work after she's finished. There are several free encryption programs. The one I used I got on
www.aamtonline.org and it's called FineCrypt. There are also encryption programs on this website you can purchase. Also check out
www.transcriptiongear.com and
www.sylvansoft.com for other programs.
There is also a free program called Express Scribe for transcribing--here's that link:

Most people use wav pedals, I do know that, but there are other programs called Start Stop, and others.
As you can see, I know just enough to be dangerous. Hopefully a more knowledgeable person will be able to help you more!
