No problem, I know how overwhelming it can be to look for gear.
You can also check out
www.productionforums.com. They have an unofficial E-mu forum on there, and they discuss the 1616. Bear in mind though, on support forums, you will rarely hear from the people who have success with the product, just the people who need "support". They do have a compatibility list on E-mu's website as well, so you might check that out.
Also consider your budget for EVERYTHING. (Remember mics, cables, monitors, headphones) I'm not sure how much of all that stuff you already have. Like I said before, which interface you get can greatly depend on what you need to record. In the right hands, any interface (well, almost any) can net fantastic results. When you do settle on your gear, take a lot of time to practice micing techniques, placement, etc... You will find that the room, mic technique, and quality of musicians will make a larger impact on your recording than an interface, as will the mics and the pre-amps they go through.
For what it's worth, I use a Dell Inspiron 8600 with
a Tascam FW-1804 ($75 rebate right now if you get one). It works fantastic for what I do, and there is lots of room to grow. I was using a Firepod (Big Brother to the Firebox), but went to the Tascam to get better input monitoring and ADAT input. However, the Firepod worked perfectly, so that wasn't the reason for changing. Really I crossgraded rather than upgraded.
Hope this helps as well.
