DON'T BUY CRAP!!!!!! SAVE UP YOUR MONEY & BUY A GOOD MACHINE THAT WILL LAST. THE GOOD MACHINES HAVE BUILDERS THAT BACK THEIR MACHINE. THAT WAY IF YOU HAVE A PROBLEM YOU HAVE SOMEONE THAT CARES ABOUT THE MACHINE RUNNING CORRECTLY. Also, with the good machines you probably won't have a problem in the first place. SAVE UP BUY A SPEKTRA OR A CENTRI. They both have great customer service & machines. (needless to say)
