Are ICOs still worth it?

Interested in getting into ICOs for the first time. Seems like a great way to maximize profits down the road.

I look at stats like these on ICOs of the past: http://ift.tt/2s8SJ4R

For example, NEO at 3 cents, ETH at 31 cents, OMG at 24 cents, and some of the other big ones on there.

Obviously, those have been insanely good RIOs.

Have a few questions:

Are cheap ICOs like that a thing of the past? Most of the ICOs these days seem to be really expensive.
When an ICO hits the exchanges, what does it tend to hit the market at relative to its ICO price? Is there a place where we can chart the ICO price vs. the initial exchange price? With this question, I'm trying to gauge if it's a good idea to get involved in ICOs or wait until the coin becomes available on the exchanges.
Is a coin always cheaper at ICO? I've heard stories of tokens hitting exchanges and immediately dropping in value with a sell-off.
Any places where we can keep abreast of new coins being added to exchanges?

Cheers,
