First thanks for blackhatworld forum members. Still i am a newbie asked here about buying UD as my first seo tool. Most told UD is best, but they compare it with licorne aio,GSA SER. So i decided to get both licorne aio + GSA SER instead of UD. It saves me $150, to be used for proxies and captchas. It seems good idea for me. I saw features of licorne aio + GSA SER on web and they did every thing, the UD can.
