How's free sound to you?
Inkscape. Draw Freely.
Many people here use InkScape, and it's a great alternative if you don't have Illy or Corel.
Just be warned...you may not be able to edit text in an EPS file that you've bought. It may have been converted to an object or curves, and may not be editable as text anymore. But you can always substitute it with your own text.
Good luck!
