Might be easiest to get either a used VCR that is still analog or a new low end on that still has analog, should be able to do it for well under 100 bucks, used one even cheaper.
Unless you plan to dump all of your tapes once you go digital then you will need a VCR anyway, if that is the case then you might go for a new one that supports analog and digital and has an HDMI output (nice to have, not required). There are still plenty of them on the market.
Here is an example from Amazon: $56 bucks referbished.
There are tons of them on Amazon, the key things you need is a NTSC Tuner (VHF/CATV), all of the older ones will have a tuner, beware of the new ones, many come with no tuner these days as they are required to support digital in new units.
If you see one you like you can post a link to it here and ask what folks think.
My VCR has broken down. I will probably have, for at least another year, a basic cable (Comcast) analog tv signal (no settop box right now) for my older analog tv. It will probably convert to an all digital signal in the future and I may purchase a digital tv. In the meantime I would still like to keep recording a few current programs for later playback. Is there a recorder that will do this with my current configuration? Will it still be useful in my possibly all digital future?
