Ethiopian Tour Companies

So, this Ethiopian training contract we’ve been working on looks like it’s getting real, and I’m figuring that as long as I’m flying half way around the world, that I should stick around and do some sight-seeing after I finish my work commitments.

That being said, has anyone here toured Ethiopia, and if so, can you recommend any tour companies? I’m not looking for anything luxurious or exorbitant, just a reputable company with good service that will set me up with an enjoyable trip and decent (bed and hot water) accommodations.

My first OP in about a decade and it sinks like a stone. I’ve found what look like some decent sources for reliable tour companies, but personal accounts are always welcome and helpful, so I’ll give it another shot and see if anyone in our vast international cabal of Straight Dopers has any experience at all with any Ethiopian tour companies.
