If you can find one at a good price, I would grab that. Presumably because they have a good reputation. Interestingly, last time I looked, the second hand units of this model were selling at a significant premium to both the price when new, and the newer digital capture units. They aren't still sold new, but there do seem to be quite a few second hand ones on the market.

I have had good luck with an external unit from Hauppauge (the HD PVR Model 1212) previously, which would do pretty much any analog resolution up to 1080i and gave good quality.

Quite a few units are over-hyped and underperform other units that cost significantly less. Some of the specialist forums review capture units, and it's well worth reading a few reviews before purchasing. I started out experimenting with a quite expensive internal capture card from Pinnacle back in the day, and the quality of the captures I got was abysmal. Some of the cheaper ones are, quite frankly, awful and won't give a good result.

Not all capture devices are created equal.
