You can find a used BlueSound Node 2 for around $300, or a "re-certified" one from BlueSound for $400, or spend $500 on a new Node 2i. It will do everything you want it to and more.
If you buy a used one and decide you don't like it, you're not going to be out too much money (if any) if you decide you don't like it and flip it. If you buy a new one, BlueSound has a 30 day return policy.
Try it and decide for yourself.
I'm running one through my Auralic Vega DAC in my main system and it sounds great. The best bang for the buck component I think I've ever bought. I have one in my bedroom and am using the internal DAC on that one.
The Node 2 sounds quite good on its own, but will sound better when connected to a high quality DAC.
Before I actually listened to one, I was skeptical and also considered it an "entry level" piece because of the low price.
