IMHO, you won't get much better than the Xara range of products.
I've used them for fifteen years (or more) and have found them to be the most useful graphics tool for vector drawing and creating beautiful (and small) bitmaps in a wide range of formats. Far better than CorelDraw and you can try before you buy. The website is at
www.xara.com.
No other interest other than a satisfied user.
