Vacuum Cleaners Discussions

We recently purchased a Sebo Felix from Costco.com and my wife does not like it at all.  It runs hot and was heavy/akward to carry as a canister.  Luckily Costco has a great return policy!  The most important feature for her is light weight and she really likes our 10-year old Oreck.  I've gone to both the Oreck store and an independent vacuum store to look and compare.  The Oreck and Simplicty Freedom seem very similar.  I like the high end Simplicity Freedom model F3700 [priced at $399] without the companion canister and $499 with the canister because it has a metal brush roll.  The lower end freedom models don't have two speeds and frankly don't seem as good as the Oreck to me.  At the Oreck Store I tested the Magnesium, which was interesting, but costs $399 as well [$499 with canister].  Also, not sure about buying this new and unproven model although it was incredibly light.  Costco is running a special thru January 15th, where I can purchase the Oreck XL & Canister companion for $248 [$50 off costco price].  At the end of the day this seems like the best value to me, but I'm curious as tot he opinions on this forum.  Thanks very much!
