There are alot of cameras in your price range (new and used) and you really need to research each and choose what you want.
Canon axh1 (new)
sony fx1(used) fx1000 (new)
Panasonic hmc40 (new and cheapest) hmc150(new or used) hvx200p or a(used)
do some research, if you dont want to use tapes then check out that line of panasonic cameras, they increase in price and increase in difficulty (hmc150 and hvx200p/a are similar)
causwell, check it out.
