Great! There are enough widely available brands of Taco's Mix.

Here are the indications I received from many of you:
Old El Paso regular and 25%less sodium, was indicated by several people
and it is also listed in the Try County list.
Ortega Taco Seasoning  Mild and Hot
McCormick's - has  potato starch as a thickener
Chi-Chi - although the GF status of the product has not been checked with
the company.

A great idea is also to make your own taco seasoning mix.  Thanks to
Gayle in Boise for providing the following recipe, that is equal to 1
package of seasoning mix.

Taco Seasoning Mix

2 teaspoons instant minced onion
1 teaspoon salt
1 teaspoon chili powder
1/2 teaspoon cornstarch
1/8 teaspoon crushed dried red pepper (more if you like it hotter)
1/2 teaspoon instant minced garlic
1/4 teaspoon dried oregano
1/2 teaspoon ground cumin

Mix all ingredients thoroughly.  Can be stored airtight (in foil packets)
for up to 6 months.  To use, add to browned ground beef along with 1/2
cup water.  Simmer for 10 minutes.

Thanks to everybody, I already tried  Taco's  based on your suggestions
and they are really good!
