I suggest you try out Xara Photo & Graphic Designer MX 2013 or Xara Designer Pro X (formerly known as just Xara or Xtreme, but they seem to like a ridiculous name now). It's really fast for a vector drawing program, and a lot cheaper than Illy or CD. I use it all the time. Gamerprinter uses an older version, I believe.
Free trials and more info on their website. Extensive forum about it here.
