Depends on what you're looking to have reviewed. Juice, VV/VW mods, or mechanicals and RBAs. Mainstream and more unicorn-ish type mods can be reviewed by various people. I would say get involved in this forum and the devices you want since you'll usually find out about what you're interested in faster than most reviewers get their hands on that particular device by browsing the threads and keeping up with what interests you.
