Focusrite generally makes great interfaces. I have the Saffire 6 USB which was the precursor to the Scarlett series. It's above and beyond what most interfaces in the sub $200 range brought me. I've been through quite a few over the last couple of years and this one is the keeper for sure.
Latency won't solely depend on your interface, although it helps to have a good one to start with, but your PC/Mac specs will affect it as well. I have a PC thats a few years old and nothing special, and I can get 8ms latency easily, I rally can get it smaller but I always monitor directly so I don't need to worry about it anyway.
Read reviews of any interfaces you might be interested in. Read reviews from different sites, Amazon, Google, Gearslutz, and see what patterns you see to get an idea if its right for you or not. Some interfaces are great and work well with Win XP 32 bit, but not Win7 64 bit, or they might work well with a Mac but not PC. It's really hard to say yes or no without knowing and reading for yourself what's going to work and what isn't. You'll for sure get lot's of 'Get this' or 'Don't get that!' but only you can decide, read up and HAVE FUN!!!!!
To sum up, without knowing more I can't say for sure, but the Focusrite is a great choice.
