Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

- Energy autonomy (hopefully the ability to remain underwater/at sea indefinitely)
- Macroscopic navigation (I heard this was a problem for AUVs, haven't done the research though)
- Cost (duh)
- A retractable pod that floats to the surface, has a GPS receiver and solar panels to recharge batteries during the day. AUV releases this pod every so often to calculate position deltas and direction of travel (while underwater and "blind", itll be trying to estimate where its going)
- Some kind of built in water wheel that will spin and drive a generator as the AUV moves through the water? So as it is expending energy to move it is also gaining some back (no idea if this is even possible/feasible)
- Using a cell phone as a GPS/wireless communication would also be pretty neat, although I'm not sure how difficult this would be

Sorry ... read the word wrong .... you don't want UAV , you want AUV ... my bad
If you're going to build it, and you're not looking to go deep (say 10m max), and you already have a metal lathe to machine end caps, and you're willing to stick with hobby-level parts, and go fairly skimpy with sensors, you might build one for under $1000...
^yea I looked it up on Wikipedia and it says it outputs less than a watt, so that's off the drawing board
While the MM-7 operates based on well understood physics, it may be the closest thing to magic and a perpetual motion machine you can buy anywhere at any price.
