One walk-in-off-the-street price for 6-3 outdoor wire comes to about

How much for a couple of used 3 kVA 240-480V transformers and skinnier
wire?

Interesting idea (and I see someone gave some ballpark figures down
yonder).

I'm wondering about losses: how much power would be lost in that pair of
xformers?

Most transformers do not have very much power loss. They can be around 98%
efficent for well designed ones to 80 % for small not so well designed ones.
