Beside my 9911 I have a JVC HR-S3902U -- a so-called "cheapo" JVC S-VHS -- and it actually gives pretty good picture quality for captures (the biggest problem with these apparently is that you can expect them to wear out quckly). Both my machines are actually pretty similar in a lot of ways despite (supposedly) being at opposite ends of the quality spectrum. Even if this SRV101 is more like just a better-built, TBC'd-out 3902U than a 9911U I would guess pretty confidently that it would be a great VCR for low-ish cost capturing if you can't afford the more pro route Moth3r suggested.

Note that apparently the TBC built into these VCR's and external TBC's (like the Datavideo) do different things. Here is a link that I've gone back to time and time again that goes over a lot of this stuff in a brief enough manner. (Look at the example pics at the bottom...)
