Depends on what features you're looking for.
Want to shoot in HDV?
It's in your price range if you go with a lower priced housing. Might have to give up manual white balance control or some of the higher end features on the camcorder but it's possible.
Sony is selling the HDR-HC5 on
sonystyle.com. They're currently in stock at $1099. It's a 1080I HDV camcorder. That also can record/playback in SD for compatiblity with standard computer systems/DVD burners for editing and DVD creation - the hardware requirements to edit in HD are pretty substantial.
It should fit into a
TopDawg II housing, the HC1/HC3 do and they're built on the same case as the HC5. It sells online for $899. It's a depth and slightly feature limited(flat port instead of full zoomthru) L&M Stingray so it's a solid housing for the money.
I'm relatively certain that the HC5 would also fit into a Ocean Images
Dolphin Pro. They're $849.
Either way you're looking at just under $2K total. For
HDV...
Either housing will also work with most of Sony's HC series MiniDV camcorders. Some of them start at under $300. Personally I'd spend the money for HDV, the picture quality on an HDTV is unreal...
Since I've never held an HC5, you should verify these assumptions with the housing mfr's.
