Please help to pick my first good fountain pen

Hey all
I¡¦m a newbie in the world of fountain pen. A few weeks ago I brought a vintage pen from an antique shop, (I think they are not specialist in vintage pen). The color is green with gold cap. The cap marked 'Pelikan 30 Rolled Gold' and the nib marked 'Geha 14K 585'. After some research over the internet I understand that Pelikan had acquired Geha many years age. So I am not sure that this pen is a Pelikan or a Geha or actually a hybrid (a fake). The nib is very smooth but the pen is too light for me. However, after playing the little toy for a few weeks, I finally fall in love with fountain pen...

I'm looking for my first good fountain pen and would like to get some advice from you guys. I want a pen with:
good watering mechanic ¡V less maintenance and less trouble,
good nib ¡V I like smooth nib,
good looking ¡V good craftsmanship but not too shining, it will be a pen for use not for showing off

After some research, here is my short list:
Montblanc 149 ¡V so famous and well known
Pelikan M805/M605 ¡V so elegant and I like the black and silver combination
Lamy 2000 ¡V everyone praise its smooth nib
Vintage Parker 51 ¡V so famous but the nib doesn't look like fountain pen's
Vintage Parker 75 ¡V classic silver look

Personally I prefer the Pelikan and the Parker 75. Since I am an IT consultant, I will user the pen during meeting with management and client, gathering user requirements and it can be lot of writing and charting. Also mention that my boss only uses BIC kind of cheap ball point pen so mine should not be too exaggerating but elegant to reflect my profession.

Please help me to pick one or you guys have other better suggestions.

Thanks
Adam
