$2,600 is an insulting price to ask someone to pay for a single certification class (only 5 days???), considering you can buy a book ($75 max) and a voucher ($200 max) and teach yourself and then take the exam(s).
You could even check your community college for an A+ oriented class, if you absolutely must have in-class instruction to learn. My community college offered the class (it was called "Managing and Troubleshooting PCs", and our textbook was a Mike Meyers CompTIA A+ book, and we used a simulator called TestOut).
The department created the class around A+ since there is such a demand. Many other colleges are doing the same thing (offering the class but not officially naming it A+). The class was a few hundred bucks plus a lab fee plus the book plus the simulator. All together it couldn't have been more than $500, but I don't remember exactly since it was one of the earlier classes I took (plus mommy and daddy paid). IMO, the book was the most valuable, as the professor just lectured on basics and history that I had already known for years. The simulator... well... simulated real world situations, and we were asked to troubleshoot them. Some ran a Windows simulator, others were hardware simulations. It gave some practical knowledge, but in all honesty, I already knew 90% of the stuff it taught.
If you really wanted to blow money, you could get the complete TestOut library for under $2000. That includes something like 10 certification education programs (which include on-computer training, lab-simulations, and exams [not the actual exams though]). They have a list of all the certifications their material covers (A+, Net+, Security+, etc...). They do work, as I've used them in 2 different classes (A+, Net+). You could probably find the material cheaper through your college bookstore though. I think I paid something like $75 for my A+ TestOut disk (costs $600 through them directly). It would be all you would ever need if you ever wanted to prep at home.
