Excuse my newbieness, but I'm going to purchase the 40D before the rebate period is over and I was wondering if I should invest in a monopod or look into a tripod? Most of all I'm looking for a very lightweight alternative to carry around with me (possibly fit in or on a Crumpler 7MDH) that will help with taking solid pictures in a Something where it's easy and quick to use which is where I think a tripod might not be what I'm looking for. Having to fold and uncollapse the legs each time I want to setup a shot might end up being too time consuming. What added benefits do a tripod have over a monopod outside of enabling you to remotely release the shutter and enable you to be in the picture? I don't mind not being in any pictures since in the last 10 years or so of taking pictures I've only been in a handful of them. 
I probably will invest in a tripod in the future but in an effort to minimize costs and efforts at the moment, will a monopod suffice my needs? And if so, any suggestions on a quality one? I keep hearing good things about Manfrotto, any particular one I should look at?
