Hot Tools, Helen of Troy, and Curl Master all make reasonably priced professional grade blowdryers. I love curl master personally. I bought one with tourmaline, and it is ionic as well and have had it for nearly three years and used all day long on clients with no problems. It also was around $50. The tourmaline is a semi precious gem that helps distribute heat more evenly on the hair which is particularily important when straightneing hair. I got it at sally's. They also make great flat irons as well :)
