Coreldraw
I have been using version 12 for about 5 years and I have sent hundreds of eps files to my Roland SP-300 which uses ColorRip with no problems at all.
I also have VersaWorks but have never uesed it because ColorRip works just fine for me.
I also have CorelDraw X-5 but I am so used to version 12 that I use it almost all the time.
You should be fine using what you have.
