In my experience, cheap tools can only go so far. Take for example the HDMI IC on the one X. Had to use a BGA station to remove it before. I upgraded to a better heat wand and it comes off no problem. Also, for removing through hole pieces (like a joystick). Best option is to use a desoldering gun assuming you are trying to salvage the part. If that option does not work. The cheaper methods are to use wick or desoldering pumps. Look at it this way, the cheaper the tool, the more work you will have to do. I hope you are not using a pain melting heat gun, if so, get a wand. Maybe your problem, those things are huge and cannot control airflow or heat.
