Wanted: Crock-pot with a Timer

Tacos.  This is now my go to recipe for days when we are both working late.  But I have never been the biggest fan of the normal, ground beef, taco seasoning ones.  Don't get me wrong.  They are good, but I really have to be in the mood for them.  I started making shredded chicken tacos in the crock-pot.  It is probably the easiest recipe I have ever made.  There are only 3 ingredients.

1 jar salsa (sometimes I get creative and use different types of salsa; black bean and corn, peach, etc.  I always have to hide the beans from Rob though.)
juice of 1 lime
boneless chicken breasts or thighs  (I have used a thick chuck steak and then shredded that.  Also delicious)

The problem is that our crock-pot doesn't have a timer.  When we registered for one for our wedding I never thought I would actually use it.  My mom never did so I didn't really see the need for it, but because Rob was obsessed with our wedding registry and making sure that we had everything that the "experts" said you needed, we ended up with a simple low/high one.  Since we get home late on taco days our meat is always overcooked.  This time I tried braising the chuck steak in the dutch oven (it was a weekend and we were home).  I think I had the wrong cut of meat and/or didn't cook it long enough because it was a little chewy. It tasted good though.

I serve these with flour tortillas (corn if my sister is over - no gluten), roasted corn (frozen corn added to a hot, dry pan and toasted until it is brownish in color), cheese, tomatoes, sour cream, and guacamole (my favorite).

These got a "good" on Rob's scale even though the meat could have been better.  I definitely need to head to the store to find a good crock-pot with a timer.  Any suggestions?
