I've used Sta-Flo (half diluted in a spray bottle. That's the cheapest. I've also used Niagara which smells great and really stiffens the fabric. (My hubby calls it Viagra for fabric. LOL). Best Press is too expensive and I didn't notice it doing any better a job, but some people swear by it. Once you see the results of using starch, you'll wonder how you'll ever did w/o it.
