MFJ power meters are fine for use in non-quantitative measurements (where you just wanna see a meter move) - and the prices are affordable, too. That's all amateurs really need, unless you're right up against that legal limit mark .... then I'd recommend an NIST traceable instrument. And while you're borrowing that NIST power meter (who can afford to buy one?) you can "calibrate" your MFJ stuff!! PS - Now, Jason, you just let him troll you!!
