If you visit their website and click on through to a webscriptions month that is out in full, you'll be able to read the first 25% of each book online as a free sample. That should give you a large enough taste to make up your mind. Or you could visit the Baen Free Library (also linked from Webscriptions), where they have about 100 entire novels up for free download.
"C'mon kid, give it a try... first hit's free!" is an effective sales approach.
