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.

When the film first started playing, my partner and I looked at each other as if to say "What on earth is this?..." but we decided to give it a chance and let it play - for about half an hour before we couldn't bare to watch any more. The title says 'Funny' - it wasn't. The overall cover is totally misleading and gives you the impression it is a funny film by someone who had previously done a funny film - but it was in no way funny at all. The jokes were terrible, the script was terrible. Very disappointing.

Fantastic book! I was kept on the edge of my seat from beginning to end! This book is definitely going to be the start of an excellent series. The novel is based back in Venice, just around the decline of the Byzantium era. My favorite characters were without a doubt Manfred and Erik.This book is an excellent buy!
