VHS Conversion Suggestions

So I know that Wal-Mart and Walgreens and other places will convert VHS tapes to digital but the cost is $25+ per tape and we have a few dozen to do.

Has anyone tried one of these VHS to Digital Converter USB 2.0 Video Converter Audio Capture devices?

Elgato Video Capture Device

Roxio Easy VHS to DVD 3 Video Converter to PC

Our VCR is dead but my grandmother's still works so it looks like I can just plug into one of those devices and record.

Any other suggestions?

From what I know Elgato is generally a reliable brand for this type of thing, but I haven't used it personally for VHS conversion.
