I only would use a black one, but if you want a color one I would get orange. Orange and black look great together. At least they did until my art teacher took them. ='(

I like the effect sharpies give, they put alot more ink on the paper than most do, perhaps too much, but they are meant for permanent. Sharpies are great for drawing, but as other have said, don't bother with coloured ones, they are overpriced and give the same effect as any other fibre tip.

I've always found sharpies, even sharpie minis, really thick and hard to hold. Whenever I try and draw with sharpies I either walk away with REALLY sore hands or a very inky piece of paper with lots of holes in it. I would recommend a few black sharpie minis, but as Azie says just use crayola or whatever for colour. It's a lot less expensive but a similar quality...

Sharpies are really hard for me to draw with but I've seen artists who do masterpieces with them.
Like IrishChaos said, they go through paper. And they over-saturate almost every normal brand, which leads to actual holes ripping in your art or warping of the paper so you would have to buy some that's thicker like card stock, something like Bristol or marker paper from Hobby lobby/Jo Ann fabrics or some other crafts store. There are some awesome art stock stores around that usually have educational products.
Other than that, Sharpies are harder to control compared to tools such as pencils or ink pens.

I'm kind of a nerd about these things ʕ·ᴥ·　ʔ

Dang, I hope you dont plan to spend your whole $100-$200 on sharpies. They can be useful, but like azie says you only need a couple.

Fine-point black sharpies are great. You don't need to budget so high... You really only need a fine-point and a fat one and that'll cover most things. I wouldn't worry about colored sharpies. Just get regular markers for that. They're cheaper and are just as good. Black sharpies are just a bit blacker though and are better quality that some of the crayola black markers that look more dark green than black.

Depends. They can go through paper, but I love doodling with a really finepoint black sharpie, so I would say yes, for doing black and white doodle style drawings.
