I don't know of any other i-banking books for you Eazyb81, but I think anyone who has been an i-banker will trash it and will agree with a lot of Monkey Business. It's a pretty humorous take on the whole thing.
I think the deal w/ i-banking is that the burnout rate is so high -- I'm just making this up, but I think like 70% of people leave after two years, maybe it's higher than that -- that most people who have been in the industry hate it. The ones that stay and rise to the level of managing director are making insane amounts of money, and while they still work long hours, they're not subject to constant verbal abuse and all-nighters, so they probably "like" i-banking as much as it can be liked.
I know you've probably heard this before, but they call i-banking "fool's gold" because the money sounds great and all, but the odds that the average person will really stick with it to the point where they're making big money consistently (making 200K for two years is nice, but if you jump ship and move to a muni bank or whatever burnout analysts do, you realize you just traded two years of your life and your health and your livelihood for something like 200K after taxes) are so slim that it's just a brutal machine that churns people into hamburger meat.
Sorry to go on a tangent there, but I've been considering I-banking myself and I know it would be a mistake, but I still keep thinking about it and ignoring all my recovering i-banker friends who tell me it would be the biggest mistake of my life.
