the time estimated is based on how long the program is. You have to record them in real time. You will need to change tapes, so you can't just let it run overnight etc.
For me at least, it wasn't worth the time/effort to do it from tape. But then again I am an old man by this board's demographics! But there was definitely time where I would have been game to tinker etc. Plus my wife would kill me if I need to spend more time than I already do at the computer
If a bunch of you guys are in the same boat, you should pool your resources and share the fruits of your labor!
