You could go for a sony FX1000, it's one of sony's newest HDV cams with best lux rating and great features. Runs for $3200 (US). I think it's currently the lowest priced advanced camera from sony right now, for wedding videographers, it is a dream come true (HD cam in the $3k range with lux rating of 1.5) and is therefore probably the camera I will be upgrading my business to in another year or 2. Right now our backup camera for weddings, and primary indie film camera is the Sony HD1000u, runs for $1500, and given good lighting, gives incredible picture.
As long as the camera is of true quality and has the features you absolutely need, go for whichever is lower price so you can get more than one, and still have enough money for the additional equipment you are sure to need. If I was running on your budget, I would take 2 sony HD1000u's over a single $4000+ camera that will probably not produce a noticably better image given good lighting conditions that I would control. You will need lighting and sound equipment, stabilization (tripods w/dolly, jib) which will add up quick as you probably know. fortunately, I think you could manage all you need within your budget.
Compare the features of your found models, and the 2 I brought up, Sony's are fantastic and I place my full confidence in any of these 4 cameras. Please let me know what you come up with, maybe a feature to feature smackdown, as I myself am curious to see how these cameras compare.
