I personally have a Dazzle Fusion i use to capture from my VCR. I'm happy with it and never had a problem. A few others on the firums have had a few teething troubles but from the threads I remember, they all got working in the end.
In fact Dazzle doa range of A2Ds. Have a look around at

The other thing that I quite like about this model is that it also acts as a multi card reader (memry stick, smartmedia, compact flash, micordrive etc etc) which comes in handy once in a while.
Of course there are many many others around that I;m sure many people will recommend. I just happen to have this one and have been quite happy with it.
