Looks at SN....TRAITOR!!!!!!
Below $150 will be hard. What style to you want? canister/upright? Care about noise? etc?

Took out the referrer codes, but I recommend if you shop amazon load the ASPCA add on so they get credit (or another charity). Easy way to give money back to society.
The Bissell Butler was a Samsung model that got rebranded once they pulled out of the US market on vacuums. I wish I knew how good it was going to be (I bought it in 2000) since it only cost me $54. I tried to buy another once mine came but they sold out. it's been 12 years and only now are the wheels failing.
It was quiet and works awesome. Bag + bagless combo.
If I had wall to wall carpeting I'd have picked a powerhead model of some sort. I only have that in my office (not by choice, they had berber installed prior to me buying the place.)
I will say if you do want to buy any of the high-end vacuums (I sold Filter Queen one summer during college), always get the final price then offer to buy the demo if you absolutely want a 'new' one. I think we averaged about 10 - 20 demos prior to a sale, so you'd get a vacuum at about half cost with 5 hours of run time tops and having to be cared for like it was china (Our demos were inspected each week, if we were abusing them they'd fine us and then give us a new one to demo).
I haven't looked at them in 20 years really, but I did encounter a newer rainbow a few times recently.
My biggest problems with these big three are they are more industrial than home. My Filter Queen worked awesome, but couldn't vacuum water and was as loud as a shop vac.
