If you had 600 dollars to spend what would you do with it knowing what you know now about IM?

I would probably use it to buy links on some other sites for a competitive niche that I have been trying to rank in....you can never have enough backlinks

I would focus on building a massive list with that money, because you can easily turn $600 into $60,000 if you focus on providing your list with great content and products. People who opt-in would already be potential customers so it makes the sales process somewhat easier.

Buy a couple domains...get webhosting...
Buy a couple templates...
Put affiliate products on them for a review site...
Build the backlinks for free...through articles, social bookmarking, blog comments, whatever it took 8)
I wouldn't spend more than $100 of that to make sales...

I would pick a good niche, hire someone to create a product for me, do the keyword research, site set up, and ad writing myself, then spend the rest of the money on Adwords.

I will buy a VB forum and buy PPC ads to my landing page which has optins and keep mailing them about the benefits of the forum. Very specific niche of course.

I would get DomainProfitter and begging the journey into the domain name business.

$600 bucks will buy you ad spots on a site or two. If you know the right site and the right sponsor you can double your money every day, easy.

I would save more money, because what I want to buy is over $1000.00 and only Apple makes it,

I think there's a lot of wisdom in that question, and also in the responses here in this thread, specifically in Ricter's.

I think people are oftentimes too quick to spend money on things they shouldn't. While I understand the importance of investing to turn a profit, people often go broke trying to make money online. Backwards logic if you ask me.

Bottom line, never, ever, ever stop asking questions, be careful before you spend money flippantly, and just try to let wisdom and common sense govern your decisions.

Buy more content... even though I create most of my own content. :-)

You can't go wrong spending money on (good) content. It lasts forever online, and gives you endless opportunities for monetization.

At this stage, I'd buy enough content to set up a blog to promote the project I'm currently working on (an ebook) - it would save me time, since I wouldn't have to write it myself.

Ricter gave a good "newbie" directional answer.. but you asked "with what you know now"

And I would say...

1. Spend about $300 of that on the top Co-Reg system for 3mths service; that's a service that builds your list for you. ($300 - listopt.com)

2. Go to Geutenburg(sp?) and find Public Domain content on the specific niche I'm targeting. (Free)

3. Break that content up into a series where I had at least 3mths worth of content to fill email messages that are sent out once a week to my list. (Free)

4. Get a Google gMail account and learn how to utilize their POP feature; there's a method to this madness.... stay with me, here. (Free)

5. Purchase "FollowUpExpert" and set it up to utilize gMail's POP server to send email. ($49)

6. Download xMailWrite as the tool to compose my autoresponder messages from the content I acquired above. (Free)

7. Go to ClickBank and do the research and find about 20~30 quality products that match my targeted niche (with good gravity that pay a minimum of 50% commission and priced no lower than $20ea. and no more than $100ea.) to utilize as paid sponsor ads in my 3mth email series. (Free)

8. Put all the puzzle pieces together and start mailing.

9. Wash, Rinse & Repeat; as statistically (doing the above with "quality" in mind) by the 3rd month you should have made at least enough to pay for another month of listop. If not, you've only spent $350 so you still have operation capital to work with from your original $600

10. Join the Warrior forum and read, read, read...

Hope this helps...
PLP,
