I haven't used Serif Draw Plus myself, but it seems to be one of those basic programs that comes in bundled packages like "Make Your Own Greeting Cards", etc.
Judging by the features described on their product page... http://www.serif.com/drawplus/drawplus5/index.asp
It has at least some of the key features you'd want in a basic vector drawing program. And I mean, it's only $50, not a big risk.
Why don't you download the free trial version, though? Click that link above and then click on the small yellow "TRY" button.
Hope this helps.
