I have a slightly smaller model of the same blaster. I bought it from TP Tools as well. It is a high quality machine, comes all ready to use...
Be sure to purchase the carbide tip. It will last far longer than the steel or porcelain tips, it is well worth the money..
The guys on the phone at TP Tools are helpful and well informed. Whenever I need replacement media or accessories, they know the score.
Make sure you have enough air to power it. After I bought my cabinet, I had to upgrade my compressor to a 5 HP, 2 Stage with a 60 gallon tank. That combination makes for a great set up.
