i tend to want a cannister because it easier to get underneath beds, tables, sofa......gimme brands and models if you can,,,XOXOXO
Sears has a very effective canister built by electrolux. Don't know model number but is priced around $450
In my opinion, I would not buy a Rainbow! My mother has one that she paid over $1000 for and I would lots have my upright that came from WalMart. You have to put water in it every time you vaccum and then empty it; in other words, it's just a pain to deal with. Before that she had an Electrolux cannister and I loved it. Like you said, you could get it underneath lower furniture. The only drawback was that it took up too much room to store. They do make an Electrolux upright now that is great. My ex-boyfriend's mom sells them. They are a little expensive, but worth the price. They pick up grit and 'fuzzies' very well. Electrolux even has a payment plan. When I buy a new vaccum, this will be my choice.
Get a Dyson. They rock! (well - as far as vacuum cleaners can rock, anyway...)
i personally use this one the dirt devil envision it isnt a canister system however it has an extension wand and some nifty attachments which help cleaning in corners and behind furniture and such and the power brush attachment is awesome for troublesome areas also its bagless so if you vaccuum up something u didnt mean to then its easy to get out :) here is a pic of it......
