Welcome Gator!
If you can be a little more specific on price(lodging+dive package+truck) per week, I could be of more help. Herman has a good option for you with GRI. Liz and Ed are great and prices are very reasonable. I booked a condo through them last Oct. for 2 weeks and loved it. One of the properties they own and a bit more than staying at the inn but it had everything I could ever need.
If you want "low cost", you can check out WannaDive Hut which is run by Bart and Bob who also run the dive op. You will not find better people to deal with than them. The Hut is much like a hotel room(bedroom w/ac, tv, small fridge, bath) and works very well if you just want a place to rest and relax. Improvements to the Hut have been made since my last stay so I'm sure the upgrades would make it even more appealing.
I have also stayed at Eden Beach which I always enjoy and is right on the water. A very nice place to stay and very convenient for that early morning dive before the sun comes up. WannaDive is on site and Bongos bar has good food and drink.
Buddy Dive, Capt Dons, Plaza, Divi, and a host of others are your options depending on what you are looking for.
Look at infobonaire.com and browse the sites for your price range, but remember to check for what is included in the price of a stay. Does it include a vehicle? Does it include a dive package? Personally, I don't hold back on spending a little extra when it comes to a dive vacation. After all, it is MY TIME to play! YMMV
