Vector Editor
| Good | Better | Best |
| Inkcape (free) | CorelDraw Graphics Suite x4 | Adobe Illustrator CS4 |
While Inkscape is quite good for free, I'm afraid my recommendation for this category is similar to the last. I would recommend saving your pennies and buy a copy of either Adobe Illustrator CS4 or CorelDraw Graphics Suite x4. The latter, while $100+ less, is bundled also with an image editor. Nice!
Conclusion: Buy Adobe Illustrator CS4 unless your budget can only be stretched to accommodate CorelDraw Graphics Suite x4.
