Suggest a low cost replacement for Dazzle Envelope Manager 2002?

[Melissa2012B]

I used to love Dazzle Envelope Manager. It allowed me to easily fill out and print single envelopes, and can check Zip+4 against a postal database, and add that to my envelope. But it was put out in 2002 and has become pretty difficult now, with Windows 7 and all. At the time they were putting it out as shareware and it was worth registering for the $15 or $20 they got for it. ( I forget... )

Now the same company only sells a replacement for big companies ( I'm a SOHO ) for around $350.

Does anyone know of a good replacement for it, that isn't real costly?
