Oh and on the cheap beat, we love Parilla Mission on 30th. Pretty darn cheap and includes a 'hots' bar with assorted stuff. I have no idea what most of it is, but it is tasty. The green bits in the white sauce, which has been IDed as either poblano pepper or nopales, is very tasty. Sadly they often make a crappy margarita, so I stick with cervesa there. Good for 'typical' mexican. Fajitas, fish, etc. Nice grill.
I mentioned this too - always a great easy, cheap and quick dinner. Those are one of my favorites too - they are "rajas" - which are sliced up poblano peppers with the cream sauce and usually corn in there too - delicious!
I also LOVE Del Sur - but it's not such a cheap place - when you order an empanada or two for appetizer, then one of their delicious grilled entrees and then an empanada or two for desert (take out) - it's not so cheap anymore - but well worth every peso! I agree it is not to be missed, but I wouldn't classify it in the cheap eats category!
There are also great empanadas on the corner of Calle 17 and Av. 20 - I want to say it is called Tres Hermanas??? It's green and open in the mornings and then again in the early evenings - really delicious local style empanadas for 8 pesos each!
Also the shrimp taco place I listed is on the transversal at 110th or 115th on the SOUTH side of the street (on the right if heading towards the other side of the island)- 2 or 3 blocks east of the NEW PEMEX that is on the right hand side as you are heading towards the other side. It's called Tacos Camaron Dorados (or maybe those words in reverse - haha)
There is also ANOTHER great shrimp taco/torta place on Juarez right at Av. 55 - just as you pass Casa Mission - can't remember the name but I love their tacos and tortas too - $25 pesos for a shrimp torta and $15 pesos per taco
Also, don't forget Camilos!!! It's on Av. 5 between Calle 2 and Calle 4 - just north of Kinta! GREAT seafood tacos, tortas, tostadas, ceviches, and full on meals. Tacos and tortas are very cheap and delicious!!!

I would also vote for Sabores. My second favorite mole, I think.
That's another one I don't get - I've been sick from there on more than one occasion! And I have a tough stomach! But some people love it
Chilangos on Ave. 10 between 13 and 15 also very good for economy home cooked lunch
OH YEH - and then there is also La Candela at the corner of Ave. 5 and Calle 6 - really good and cheap breakfast and lunch! Different meals each day for $50 to $60 pesos!
Also Contento Corazon - on the corner of Av. 10 and Calle 2 - breakfast and lunch!
There is also a new place on Salas between Av. 5 and Av 10 - don't know the name of it - but getting good reviews - it is on the right hand side of the street just before the corner of Av. 10 - next to the original La Choza
Girasoles is also really good - on Calle 3 between Av. 10 and Av. 5
And Cozumel Bakery - for breakfast - corner of Av. 10 and Calle 3
There are soo many!
