HTC is fantastic! i had my belly-button piercing re-done there years and years and years ago at the Tempe location and was super-impressed with their professionalism, knowledge and cleanliness.
Recently i decided it was time to re-pierce my ears. Somewhere along the way i got lazy and the holes have been closed for at least 5 years. Ever since my 1st experience with HTC i knew that i would never ever ever let a piercing gun anywhere near my ears ever again.
But now that i live in Glendale i REALLY didn't want to drive all the way to tempe just to get my ears done. And then i discovered there was a shop in Phoenix. i literally turned my car around and went straight there.
When i walked in they were friendly and helpful (as always). They asked all the right questions to make sure everything was exactly what i wanted. Sure, it's going to cost more than a lot of places, but the quality and the service is WELL worth it. "You get what you pay for" isn't always true, but in this case, it is.
