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.

Honestly, if you knew about the blu-ray format and the capacity 1 disc has you should be appalled that there isn't the entire peanuts collection on 1 disc. This is such a obvious marketing plot to extort more money out of the consumer. If you buy this disc you are only feeding into that disgraceful behavior. If you don't know, blu-rays can hold more than 10 times the amount of content a DVD can hold. The entire peanuts movie collection can fit on to one blu-ray disc and to seperate them over 10+ discs just takes more money from you to send their fat kids to college. A pox on both your houses.

I have a question for the continuity people.....I liked the rest of the movie, but was upset to see one thing.....why is "Eagle's" ascent stage still on the moon when the autobots go to visit the wreckage? I mean, come on, guys....any 60's space buff would have noticed that error....
