I'm imagining it's pretty difficult running it without a remote.

Yes, but you get a remote with the player, so I don't understand why you're worried. Read the FAQ on what comes with the player when you buy it.

Or are there other remotes out there that would work with the Empeg as well?

By default, the Kenwood KCA-R6A remotes (very common, available many places) also work. here is a guide on what the buttons do.

Spend some time reading through the FAQ while you wait for the player.
