If it's within the OP's comfort zone, he may want to ask the electrician
to recompute using aluminum conductors. Cut our parts cost in half.

Any disadvantages of aluminum for Main's wiring vs. copper (other than
snob appeal)?

[I know that for circuits, aluminum has had problems in the past]

Also, is it really true that the biggest parts cost may be the wire as
opposed to the panel, main breaker, grounding rods, meter box, and
miscellaneous connectors?

Thanks,
