Student Loan Consolidation

After the many years I've spent in college, and the many years I have yet to come, I've certainly racked up my share of student loans. There are a few companies out there to help consolidate them, and I've looked into many. Then of course after you do choose one, it will probably be bought out by another company, so maybe they are all the same one. I'm not sure, but remind me that I have to consolidate once again, as I seem to have two companies asking me for money now. Yuck.
