Here are my thought and I am not trying to take the wind out of anyones sails here...

That is a map of all the current MECP Master Installers (still with a valid certificate, it is only valid for 4 years)
As an Advanced Certified Tech I can say I see the pros and cons of the process.
First I will list the pros:
Can help in pay increase, promotion (usually the big box stores, circuit city, best buy, etc. etc)
Can help make the buying process for the consumer easier seeing the certificates on the wall...(this however is a double edge sword, I will explain later..)
Pride ( it always feels good to accompish something for yourself)
The new study guides have more updated information, they have also just revamped the master's test..
Cons:
Shops usually want someone with experience... (in my own practices if I have to choose between hiring a guy with MECP and no experience or a guy with experience and no MECP...I am taking the guy with experience.. every time..)
How much credibility does it add? Most consumers see the certificate and ask what it is... when you then tell them what it is they usually have a comment like ." they have a test for this?" If we can get the MECP program to be as well recognized as ASE then we will have something here...
Now in my opinion here are my thoughts....
The basic installer test anyone who can read and comprehend reading should be able to pass this test with the lowest passing score....
The Advanced Installer test... for me this test was very very easy... but to each their own.. This test should be in my opinion the basic..
I have 5 months to take my Masters Exam or I have to recertify Advanced again, I have just not had time to take the test. If you study all the recommended readings you are really getting into some advanced stuff.. Loudspeaker Design Cookbook is a fun read!! The Masters Study guide has some good stuff, leaves some to be desired...
In all, to make a long post short..... if you are already in a position where this can make you more money, better position...do it...
If you are doing this hoping to get into the industry... you might be better off asking a local shop if you can be an unpaid apprentice...
Just my .02
Oh and for the double edge sword part.... If you are the only certified tech in the shop, be prepared to have a larger work load... Customers will see your certificate and only want you to work on their vehicles..
