User Review: I'VE USED THIS VCR FOR OVER 10 YEARS, TAPING, PLAYING, DUBBING AND IT PERFORMED WELL. The picture was good, the sound, even though mono, is a high fidelity sound, which is about the closest you'll get to hi-fi and is pretty good. It never broke down. I put about 15 years of use on it in 8 years. So if you're an average user, it would probably last you 15 years, as much as one of those 500.00 vcrs. If you need a vcr, and you can find this model but one not used so much, it's a good deal. I still have it now. The heads need a good cleaning but all functions of the vcr work. Of course it does not have digital tuner so must be connected to a cable box or digital converter box to tape off tv. To play tapes you need nothing but any tv and this vcr. If this model is unavailable, look for it's successor. Today, 2010,  no one is making stand alone vcrs anymore and the ones in the combo players do not function to the higher standard the older vcrs do. The problem with buying an older vcr is eventually the parts will wear down - you just have to be able to determine how much usage was put on the machine. or buy an older one and have it serviced by a reputable shop, and have them clean it (manually, not with a head cleaning tape), replace some of the old belts, etc.. Avoid buying auto-head cleaning vcrs, they make the heads wear out faster. Avoid Sony models after 2003, they are not the same quality. Sharp models perform well, toshiba has high marks in most reviews. Do not buy a go-video duel head vcr, they are absolute junk. Do not buy a vcr with less than 4 heads or that doesn't record in slp mode (gives the most hours per each tape) don't be fooled by vcrs that say commerical skip.  Many just advance the tape 30 or 60 seconds. You still have to manually manipulate it. Exception is the Sony, it really does do that function as indicated.  Do not buy a vcr that does not come with a remote or manual - you'll be sorry. And finally i'd lean toward Panasonic because they still offer tech support on old vcrs as opposed to a company like Sanyo that will not talk to you because they no longer provide any support for any of their vcrs - any! And they are very disconnected from your problems or questions on these vcrs.
