Well, with a product like that you are pretty much trading quality against price. The cheap ones won't last, and the good ones are pricier by a good margin. Ever consider buying something from a thrift store or pawn shop? Selection is getting pretty good depending on if you know where to look. Often second hand shops near upscale areas carry very nice merchandise at a very attractive price. (West Hollywood is fabulous for this - the gay couples break up, one moves out and then other just tosses out there parters stuff just to be *****y. They have NICE stuff, too. LOL)
I like the feature set of my hp 7410 but they are NOT built to last ... However the auto duplexing is very nice and its reasonably fast. That all being said, if you have second hand shops nearby many of them can be found for about $25 which is a great deal considering that if you keep your eyes open the high failure rate of the ink carriage piece (which is "non repairable" - unless you are like me and determined enough) means that a great many end up out on the curb. I cannot in good conscience recommend anything by HP unless it is secondhand for that matter, because they are overpriced for what HP considers a disposable piece of hardware. Go with something by brother if you buy new, they seem to be longevity minded.
But seriously, here in Los Angeles there are positively multitudes of document feeder scanning auto duplexing copy faxing wireless network card reading HP's going for 35 bucks and less - sometimes with dual paper inputs and ink cartridges still in em. Chad found the first 7410 on the curb and brought it home - didn't work but I fixed it with one of those circuit writer pens and some tape. We just a second one for 25 at Out-of-the-closet that we were gonna use for parts, but that one works, so now we have two. =D Comes in very handy for archiving grandads physics articles.
