WHAT BRAND OF CENTRAL VAC and power head would you recommend? - central

We had an Electrolux vacuum cleaner to replace their central for 17 years and the need for heads of energy and some accessories too.

After checking a few places ... seems a better option to buy buy a new set only to accessories for the replacement (although our central AC unit is still valid.

We saw a road and a Canavac but some comments from other concerned central vac.

We would like central vacuum, when the power is the money or cans on the market and less noise and pollution superior.

--- So many choices, each asserted that he was the best .... What should I do?
