Best IDE for Newbie?

[Newbie via Digitalmars-d-ide]

Hello,

I have to start a new project and I want to try D instead of
using a combination of C++ and Perl.

But what is the best IDE to use on Ubuntu/Debian with gdc? I have
read of Mono-D and Eclipse.

Debugging is important for me. My programs should run under
several Linux Systems. I do not know if D really works for me. I
think it is a very promising language. But before I invest much
time in it, I would like to know if there are working development
environments. What your experiences, recommendations?

Thank you in advance!
