I wanted to put in a sidewalk that required about a yard of concrete. Delivery of pre-mixed concrete by the cement company was about $50.00 per yard. However, they had a penalty for anything under 4 yards... $200.00 delivery fee/w3tcompact/icons/shocked.gif. The electric mixer that I bought was on sale for $139.00 and the concrete bags ended up being about $35.00, so for about $175.00 I got the mixer and concrete for the job and saved about $75.00. <A target="_blank" HREF=http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=6970&langId=-1&catalogId=4006970&PHOTOS=on&TEST=Y&productId=21914&categoryId=149>It looks alot like this one</A> at Northern Tool, but has a wheel for a handle instead of the lever, and is yellow instead of red. I beleive I purchased it at TSC or Quality about 5 years ago.
The mixer will hold about three 60 pound bags at a time( or two 90s), although I find it mixes easier one at a time. It has a 1/3 HP 110V motor that will run off of an extension cord pretty easily. It is light enough that I can roll it right next to a hole, mix the concrete and pour it right in. Then move it to the next hole, etc...
It is by no means a heavy duty tool, but I've used it for one or two jobs a year for the last 5 years and if that's all your are going to do with it, it will suit you well and last many, many years. I am very happy with mine. Hope this helps /w3tcompact/icons/smile.gif
