Adding to what ItsJustMe has said,
Techmoan - Techmoan is a very good place to start looking.
In amongst the usual dross, I've picked up some excellent cameras, the Mobius, SJ1000, Mini 0801 and I now can add the TCL SVC200 to that prestigious list.
I'm pretty sure your budget covers all of the above, and the SVC200 might well be the best. I own the Mobius and the SJ1000 and they are pretty great, with noticeably different features. Have a quick glance through and see if you have any personal preferences.
