@Eddie Starr, I think that almost all of the knowledge that you need to be successful is available via the books, podcasts and forum post available on BP. What guru's sell is the allure that there is some easy way to achieve your goals, if you can just cough up significant sums of $$$. My recommendation would be to identify what problem you are aiming to solve with a guru and once you have done that you can likely come up with alternative, free, means to achieve the same. Some examples are:
1) Lack of knowledge - all the info you need is available on this site or in the many great books available
2) Lack of experience - partner with someone to get experience, there is likely some value that you can bring to any deal whether it's skills, money or time
3) Lack of connections - seek out partners on BP, broadcast what you are trying to achieve, join local REI groups
You get the point, guru's make it look like it is all easy and automatic. In reality it's about taking action, learning from your mistakes and finding partners to complement your owns skills or gaps.
Good luck!
