I stopped thinking and went to action a couple of moths ago; it was a pretty straightforward job, took 4 wooden bars and lifted my desktop to about 106 cm. If you like to do it yourself, measure to achieve a height where your elbows would be exactly at keyboard level. I can stand and type with my arms in a natural relaxed position. As I don´t *always* want to stand, I use a fancy barstool, so I can sit when I like.
I´m an old-scool designer (55 years old) and started my job on drawing tables like engineers used to have them, the board tilt to almost horizontal. I worked on final art ant typesetting montages on Schoellershammer Cardboard with rubber cement, that kind of stuff. I still can bite my ass for having sold the table 15 years ago... worst error ever. When i started working sitting down, my physical condition degraded rapidly.
All day standing, however, isn´t all to healthy... but you will be very much more mobile, step back from your monitor, walk around and come back, it´s an outright more physical approach to desktop working and on long hauls you will sit and stand, both as long as you like. Don´t think a lot about it- give it a try.
