New Audio Interface Help

I am thinking of being in the market for a new audio interface, and possibly selling the 1616m. I'd like to look into getting an interface with at least 4 mic pres (8 would be fine as well) and that has solid driver support. I know the Roland products rate well here, and was going to look into the Quad Capture but unfortunately doesn't have enough inputs. The Octa capture is ideal but runs $700. Too bad there isn't an in-between product like a Hex (6) capture.

The only thing about the 1616m I like was that it has the turntable preamp and input, since if I decided to sell it I would have to use an external phono stage before inputting it to the interface. 

What are some good interfaces that may be worth looking into, and has fairly low latency? I know about the FW and needing the TI chipset but since I may use a laptop on occasion I think I may look into getting an USB interface. I can do up to $500, else I could go up to $700. Selling the 1616m would give me a head start on saving up for a better interface. 

I had a Tascam US-2000.  It worked OK but the audio out (for headphones and studio monitors) was noisy so I sent it back.  May have just been that one unit? 

I bought a Roland Octa-Capture and it works great and in a way glad the Tascam didn't work out, even with the higher price of the Octa-Capture.
