If you are talking simply transferring VHS to computer hard drive, making the video available for DVD burning or just long term storage, I bought a Diamond Multimedia VC500 One Touch Video Capture Device. It just plugs into your VCR through the analog jacks, then to a USB port on your computer. Then you just select the drive to save to, hit play on the VCR, and hit record on the little device. The software cd comes in the box and it's really simple and basic. I also have a seagate external hard drive that is 1.5 TB. I use that external hard drive due to the fact that the digital video output file is larger after being converted. Some of my Husker tapes I've converted have been up to 8 GB after transfer. So make sure you have plenty of space.
I got the VC500 device and software for 30 bucks on Amazon. The hard drive is a very good one and very expensive but I got lucky as hell and stumbled upon mine in EBay and stole it for 60 bucks. It's a small investment, but it's a one time deal and if these vids are important you should do it. I notice my older VHS tapes really starting to deteriorate and it's difficult to get a smooth playback out of some of them.
