take a look at presonus stuffs ... can't complain of it. cheap and quality, allways working. something with 10 inputs is cool.Me too, a nice new SM57 arrived in my Christmas pressies so I am browsing for the best (value for money) interface to feed into my Mac (starting with garageband) M-audio looks ideal............oops thread hack
you could find a presonus firepod for very cheap ,on eBay, it's discontinued, and replaced by improved versions, but still working since about 10 years.
a friend of mine had problems with m-audio sound card. complicate. and she had to return it.
i don't have an sm57, maybe one day, it's a classic, and you can also mod it to the early better sounding sm57 specs ( plenty of infos on the web ) . but i'm so glad i did something crazy, buying some ribbon mics, SE R1, fantastic for the price, almost as good as some legend mics. in the beginning they were 1000 $ each ! and i got them for 300 euros both !
it captures tone so easyly, no need to try hard to place the mic, you just put it somewhere .... lol , and that's all !
it's the most natural sounding kind of mic, with a metal plate 1.8 micron thick !
and with two, you can do a blumlein stereo arrangement.
