Yeah, I got the sense that Harbour Village is for people with a lot of money who aren't that obsessive about the diving.. any downside of Eden Beach? Good house reef?
Eden Beach will do very nicely for your beach requirement. Check out the top 2 web cam views, these are on the beach at Eden Beach. Bonaire WebCams - WebCam Overview
In addition, Wannadive is one of the best dive ops on the island IMO. You will not find nicer more bunch of guys to work with.
The one big issue for me is the resort dive is one of my least favorite on Bonaire. It is mainly coral rubble with little live coral. On the up side there are 2 wrecks in 60-80 ft of water by the resort. Funny thing is, the only thing between Bari (Sand Dollar) and Eden is Den Laman. I found once you get a little closer to Buddy/SD the reef picked up quickly. Depending on which way the current is running it makes a good one way dive from/to Eden-Buddy (or Sand Dollar)
All in all, Eden might work well for you and it will certainly be less expensive.
