I do gutters with a backpack too. I'd probably use a handheld if I had one. But the extra power can come in handy. Often I'm able to blow out the downspouts completely. I charge $1-2 a foot. I can do an average roof/gutters in 5-10 minutes. Real good easy money if you don't fall off.
i love doing gutters great money usuallly not too difficult but i dont let my employee on the roof only me
