Retractable Clothesline

I would like to put up one of these, and our Lowes does not have any.
I was wondering if any one here has used one?
what did you like about it, not like about it?
Does it stay taunt, hold heavy items like jeans?
What brand did you buy?
ect ect


With electricity getting so high, and going to be higher, I am going to be hanging out my laundry, and I would even like to put one up in my house to use in the winter. No more dryer for me!

On top of that I am working on my hot water heater usage as well, so any tips there would be equally appreciated.
