Hi,
No, sorry, there's no source other than the server itself.
I'm not sure downloading an entire state at all detail levels is really a good idea. That's a lot of data on the 1 meter aerial level. How large is your hard drive?

I'd try disabling some of the smaller tilesets which will decrease the time and space taken exponentially.
E.G. you might be able to get the whole state at 16 Topo and Aerial, but you may as well forget 1 meter and likely 4 meter as well.
