The stove trick is one that's pretty commonly used. A heat gun will run you about $20, and is much, much more powerful than a hair dryer. There IS a big difference, and on a pretty huge heat shrink sleeve like one that would fit over a racquet, you may not get even/nice results with a hair dryer (most likely you WOULDN'T, unless the hair dryer was a professional one, or very, very high wattage).
