No problem - you're welcome. I know it's probably not a lot of help in the "buy this one 'cos that one sucks" sort of way, but it should at least be reassuring from the point of view of knowing that neither one is a lemon and that both are capable of good results.
The one thing I forgot to mention is that, like most Firewire interfaces, they can sometimes be sensitive to which Firewire chipset you have in your host PC. Focusrite have a short article about this in their answerbase here
. There used to be a longer article listing compatible cards/chipsets, but that seems to be offline at the moment while they update it. Similar information is probably to be found somewhere on the Steinberg site or forums. In general, I think that most things with Texas Instruments (TI) or VIA firewire chipsets tend to be OK, although there are almost certainly others that work too.
Whichever you choose, have fun!
