Thanks for the response Guys.
I didn't have much experience with TC monitors. I did try with one HP product on my WDP, didn't know what was wrong but the touching sensitivity were to low, inaccurate, (priced twice as normal one) I did calibrate the touch but still unable to gain better work. So it is now stay as my pending experiment.
I Actually need some of it to be installed in emergency department in which the doctors and nurses will reduce a pinching difficulties on the mouse and keyboard in given emergency situations. They will easily pick up which patient on the screen before aiming the bar-code reader to any medicines or medical supplies they take from the cabinet. For the time being I consider using touch pen as temporary solution. (but it has to be tightly chained to the monitor as someone might accidentally throw it away and makes other coworkers shout out in an anger).
For daily office work, all combined peripherals are OK to me. I have my screen upside down and almost flat at my desk, and set the screen rotated 180 degree. Fun at work I guess.
