Full tunnel VPN possible with "home" VPN routers?

Hi all,

I'm considering setting up a VPN server on my home DSL connection,
where I can use a VPN client and have all my Internet traffic appear
to come from my home DSL IP, rather than whatever IP I'm using now.  I
surf a lot from public wireless access points, and I would like a
secure layer of encryption.  Also, I travel a lot in China and other
places where they censor Western sites or allegedly snoop on traffic,
and I'd like to bypass/encrypt everything for security as well.

Therefore, I need a "full-tunnel" connection, where ALL traffic is
tunneled through the VPN, not just those for my private home subnet.

Because it's just for my personal use, I don't want to spend thousands
of dollars.  So I'm thinking about getting a "home" router with VPN
capability, like Netgear FVS318NA, Linksys BEFVP41, or similar and I'm
wondering if they support the full-tunnel mode of operation.  I would
be using the router as a VPN server, not client.  They advertise the
VPN capability, but I'm not sure if it's "split tunnel" only for the
private home subnet, or if it's "full tunnel" for all addresses.

Thanks!
