Any reason not to buy the cheaper one?

Absolutely not. In fact, with the exception of a
proprietary motor (like say for a Unisaw (1)) there's no
reason at all to continue buying motors from Delta.

(1) Actually, a new Unisaw motor can be gotten from Plaza
Machinery for $250-$300 so there's no reason to even buy
that from Delta.

Any other places I should look?

Plaza Machinery

Electric Motor Warehouse

(unless someone here has one to sell, I'd prefer a new motor from a
reputable dealer who can deliver from stock)

I agree but I've bought a thing or two off eBay and got a
pretty good deal. Usually in this case it's best to find a
local seller so you can check out his/her wares before
paying.
