@Windchime - Hey, I wouldn't worry about being wary of shareware sites. Being cautious is sensible, and may well help you avoid trouble. My friend develops shareware games and I help him promote them, so I know a few things about this topic.
Firstly I think you are better off looking at established sites or forums. Places where developers socialise online are more reliable than trawling the web for leads. You could ask about whatever you are looking for there.
Generally shareware costs are quite low, and people tend to use things like PayPal over credit cards to accept your payment. Someone like my friend isn't set up to accept anything else, it's just not cost effective.
Finally, I would avoid free shareware, unless you can really trust the source.
