Soundcard/mixer/interface

My old alesis multimix firewire 8 is starting to fade. I've had it for about 6 or 7 years and it's on constantly as I use it for my sound card. I want to move to a USB connection and I see 3 that seem to be comparable (to my old alesis) choices: 

Alesis MultiMix 8 USB FX

Allen & Heath ZED-10FX

Behringer Xenyx X1204USB Yes the alesis was a pain to set up, but once I got it it's been just fine.  I know I will get responses outside of this but this is the criteria for my needs 

I want all 3 in the same unit,  Soundcard/mixer/interface. I do not want to deal with multiple devices. My needs are simple

$100-300 range

I do not need more than 8 channels

The easiest integration with Sonar XI Producer If anyone has any other suggestions for a unit that I missed, please respond. If anyone has had any experience (good or bad) in using one  of these units with sonar, please respond.  Thanks 

thanks beagle, but just to confirm;
 it will function as a mixer/soundcard/interface?
and it does easily integrate with sonar producer?


on the , Allen & Heath ZED-10FX I couldn't find whether it USB 2 or 1.1. It seems like they all ought to be USB 2 now (closer to firewire speeds)  but I can find very little reference about this

Alesis MultiMix 8 USB FX may not have 8+2 discrete audio channels into the host the way the FW does, just the stereo mix. Also, it may not even be USB 2.0. The Allen & Heath ZED-10FX also seems not to have 8+2 input channels to the host. In other words, you cannot capture the 8 separate input channels at once from either of these. I mention this only because the Alesis MM 8 FW you have does support recording all 8 channels at once, in case you have been depending on this.

As mentioned, with mixer 'boards', you need to read the fine-print to see if it has multi-channel usb capabilities. Often times, though they have multiple channels on the mixer itself, they may only have a stereo mains input to the PC. I just the other day was looking for an audio interface and was considering a 'board' as a solution (I need mixer and FX capabilities), but dropped it once I realized that it could be an issue.

I went to the used market eBay; managed to find a new-unused (opened box) Motu Ultralite MK3 just at the very outer limit of your budget, but others, maybe not quite so new, have gone for even less. They have two pre's plus six more balanced ins, 8 balanced outs, all inputs and outputs are available at the DAW (USB or FW) , and it functions as a mixer (good for tracking) as well.

Getting one of these for a reasonable price on eBay is doable if your willing to sit on an auction in its last few minutes. It's a pain to do, though in my case, available fundage necessitated it...
 

If you can save a little longer and increase the budget to $499, I'd look at the Presonus 1818VSL.
8 analog channels of I/O (with preamps)
Basically a full digital mixer sans the hardware controls (controlled via sofware)
 

Well then you can save up and buy a control surface with lots of hands on control. 
 
You see at your price point, you'll not be getting everything your wishing for. 
 
An interface is the heart of a DAW recording system, to try and combine this in a budget swiss army knife mixer would be a compromise. 
 
Your looking at big bucks for a real integrated digital mixer/ interface system.
 
The entry into a multi channel DAW recording set up is an affordable multi channel interface and a controller. Two channels is fine if your just one person and do not plan on recording real drums etc. 
PS- I had the Behringer mixer and the audio interface is a real turd. No way to monitor playback from the DAW without huge latency issues. The mixer is broken now after only a few years of light duty use.
