I've heard of those certs before but I've never actually met anyone that had the CEH, ECSA, or LPT. If people in the security industry don't know that much about those certs you can rest assured that HR folks are not going to know anything about it. To me it sounds kind of corny.. I'm not sure how a test or a 5 day class can really judge how ethical you are.

If the course objectives meet your needs, and the cost is right, go for it. It doesn't sound like you are taking the class for the certification. If you want to take classes to get certs I would focus on CISSP or something focused in on your OS of choice.
