Ideas for small office w/sonicwall tz200 & dsl needs options for when dsl line goes down

hi, ive a small office client with 3 win 2008 servers , etc... we use a sonicwall tz2000 to goto internet via dsl with local isp. we use a mail server thus the outbound smtp server must be on our network, in other words we can send using the isp outbound server because we're on their dsl circuit. other than that the sonicwall also connects to my office sonicwall tz200 as vpn for support.
recently the dsl went down, and our isp sent tech to check dsl modem, line, etc.. and said it was verizon circuit issue, then we had to wait on verizon to come, and then for them to do the work at their c.o.? either way we were down for almost 3 days.
we need another solution as an option if this happens again. the sonicwall and the servers are failrly new so im interested in options for when the dsl line goes down, we really need our mail to come in/out moreso than surfing the net....

i understand the tz200 has some form of failover options, but i think its a hardware failover in case the sonicwall fails.

im not 'against' changing our popboxes from the dsl isp to a generic online mail service thus we dont need to be on their circuit to send outbound mail from our server [our server connects to the popboxes and pulls the mail down to its mailboxes accordingly, and uses the smtp server of the dsl isp to send all server outbound mail.]

i did a little research here on ee, and saw some options however these were a few years old, and i assume there newer options available these days.

    Straight from Sonicwall website

    Automated failover and failback and multi-WAN capabilities ensure continuous uptime for WAN connections including VPN tunnels by diverting traffic over alternate 3G WWAN or Ethernet WAN connections in the event of primary connection failure.

    Looks like you can do what you want to.

    I would suggest you first look at configuration guides on how to exactly do this, but basically all you have to do is get another provider to deliver a circuit for you (since you are using DSL I would suggest going with cable internet,) then set up your Sonicwall, and finally configure your DNS settings on the internet so you have a second MX record pointing to your new public IP.

    however we have other offices connecting to this office via the public ip address which is the sonicwall, so the second circuit would need to also have some .
    ill get the sonicwall guides and config what weve got.
