We are very happy to be a part of CompTIA. We have gotten way more than our $250 a year from membership. The webinars, the events, the free employee handbook - just some of the plusses.
The discounts on test vouchers has helped us get our techs certified and being a CompTIA A+ Repair Center is great advertising.
CompTIA is truly an organization that cares about the IT Channel and does everything they can to promote it. I wish they were promoting the SMB reseller a bit more.
CompTIA now does $20 a month memberships that cover your entire company so there is no reason why not to join.
