I purchased the LG cordless from Costco last fall. It was originally priced at $399 but I got it on sale for about $75 less after taxes. I have a long-haired dog, so I vacuum nearly every day - it's working extremely well for me. I bought it on the recommendation of a good friend who has 2 cats and also vacuums every day. She's had hers for about 4 years and is still using the same battery packs. I expect to have to replace the batteries eventually on anything cordless, but I'm very happy with this cordless vacuum.
