I took CCNA 1-4 under Roel Laranang and I can say its worth it, discussions and lectures was so precise and delivered in a very clear way. Devices/equipments and hands on training was very helpful and with free manuals you can review while troubleshooting. I was able to get 1000/1000 perfect score when I took my CCNA exam last October 17, 2012. I am now just waiting for my Cert. =)
