Red Heart is my default yarn for crochet projects.  I highly recommend it.  What I cannot recommend is the price.  I bought a skein of Super Saver Economy Yarn, Grey Heather in early October of this year, from this page on Amazon, from Supermart, I believe.  It was under $3.00 then ($2.79, if I recall correctly).  Imagine my disappointment when I tried to order more less than a month later and the price had jumped to $7.03!  Just a few days ago, Joanne's was having a sale on the same yarn for $2.49.
