Re: Hello there great forum. Question on VHS conversion
First, welcome to the forum!
Second, in answer to your question, I haven't, but a few years ago I was in the same position as you. I looked at the prices of commercial copying services and figured it was way cheaper to do it myself. I think the 'break even' point was something like 12 hours of tape.
If you don't have a DVD recorder and you're getting one specifically for this task, there are dual VHS/DVD recorder machines available, so you only have one box to deal with.
The downside of copying for yourself is that the recordings have to be done in real time (i.e. a 3 hour tape will take 3 hours to copy) and you can find the process drags on. We found it was easiest just to set one recording up each evening, watch something else on the TV or do other things and set a kitchen timer to remind us when the recording had finished.
I would, however, strongly recommend archiving VHS material, because the tapes decay with time. E.g. we found that some of the tapes we were copying were already showing signs of decay after only a couple of years, and they'd all been kept in supposedly ideal conditions.
So, not perhaps the precise answer you were looking for, but I hope this helps.
