Get the pet dryer versions, you usually save a good amount of bike specific versions and they are exactly the same. Wear earplugs, they whistle like crazy over the bike, but do a great job.
I have a metrovac sidekick blaster. It's powerful, filtered and warms to something like 10 degrees above ambient. Perfect for the bike, bit small to do an entire car with but great for wheels, grills, mirrors, handles and anywhere else that traps water that then slowly drips down the panel for the rest of the day
