I stick with the big three for all my gear and for the most part use Hitec servos. For the price I get them for when they are on sale I don't want to take the chance of loosing a plane with brand X from China. If I was building a cheap plane from foam or something I would give them a try.
As it is I have a big box of servos from days gone by so I don't need to buy new ones very often. Last servos I bought were Hitec HS 81s and some HS 55s. I got them from my LHS for the same price Servo City had them plus he just happened to have them in stock.
I do like digital servos and even the lowest price Hitecs I bought when they were first hitting the market are still with me. The only servo I will NOT buy is anything with Carbonite gears. They are too brittle and tend to break. Something I would like to see pulled off the market. I bought some really good servos with carbonite gears and they are limited in there use. I bought them long before Hitec decided to warn people about there use. Even then it was only on there web site or if you asked there service center directly. Carbonite Gears=total crap!! For Shame For Shame Hitec!!
Sort of like the whispered warning JR gave us about brown outs!!
