[Q]: About four weeks ago, I purchased at a Home Depot in Florida the Plasplugs "Master Tiler", model number: DWW180US-BX.I am using it for a porcelain tile installation. The original blade worked ok for the initial cuts, but I need to replace it for the proper blade type for the tile. I had bought a porcelain tile replacement blade from a blade mfr when I bought the saw. When I got around to replacing the blade, I found out that the Plasplugs machine uses a different "arbor" than everybody else. The replacement blade was worthless to me.I then called the Plasplugs US office to order the "high glaze" blade. Much to my chagrin, I was told the "all blades except the standard have been discontinued".I just bought this saw four weeks ago! I think it is very irresponsible for a manufacturer to behave in this matter.You can be assured that I will avoid any Plasplug product in the future.

[Q]: I was introduced to this book this summer by my aunt. She recommended it as one of her favourites. So, I decided to give it a try. I found the beginning a little slow moving. Once I got into it I couldn't put it down. The story is starts at the begging of man and is based on the evolution of man. Ayla, the main character is left to die because her clan was killed in an earthquake. She is adopted by a passing clan and brought to live with them. The story deals with her acceptance into a very different community. She is cast as an outcast from her clan because she is different. In fact she is one step above them on the evolution scale. In the end she is exiled from the only family she has ever known and goes on to search for people like her. I enjoyed this book alot,especially learning about different plants and their many uses. Jean M. Auel wrote a wonderful book and I can't wait to read the rest of the series.
