^ you may be waiting for a verrrry long time then. This machine is amazing. If you are unsure but want the least amount of maintenance, grab a pro. That way your "risks" are a little less with a few less moving parts (hammer, snake jaw, etc) and you get it at a cheaper price compared to the LE/Premiums. Also, you can always upgrade if you decide you want the machine but with the few extras that are mentioned above. . Win-Win.
Metallica is such a fun machine.
