This book came out a long time ago. I read it when it first came out and it introduced me into the world of ghosts and and lore. I was 12 years old then in 1982 and even now when I pick it up to read....it still takes me back to the feeling...when I first picked it up and sent shivers down my spine...in a fun way of course. The stories and the drawings were perfect together. A great book. I have all 3 volumes now and I hope he comes out with a 4th one soon.Thanks Alvin and Stephen for scaring the pants off of me when I was 12.

Wow..thats basically all i can say. I bought the cd, then realized that they were playin live like 20 minutes from my house. They put on an amazing show! They closed it with do you call my name, then went backstage. The crowd started chanting, "ONE MORE SONG!!" The drummer came out and started playing again. Then all the rest came back out and played one last song. Ra is underrated and a great bunch of guys. I got my cd autographed by all 4 and i got a picture with them. Buy From One, Duality, and SEE THEM LIVE!! My ears are still ringing.

I bought this since the big MK I also use was too heavy and messy to take into condos. I rehab ocean condos and lug all my tools into the condo for 2-3 months (compressor, table saw, router table, etc). So I focus on portability first.However, the instructions were limited, the arbor allows the blade to not spin true, and the setup screws will be quickly lost after unpacking.But strangely - the saw and fence quickly cut straight after you allow for the width of the blade wobble. Angles require some extra work. I used a 7" speed square against the fence for diagonal cuts. I haven't tried the 1.3" cutting depth yet. It should do it. But for how long? I don't see it as a long term contractor grade saw but as a saw that can be used for 2-3 yrs with about 2-3 jobs per year.
