New to streaming, looking for a budget streamer


I live in the country and up till a couple day ago my internet service was not suitable for hi-rez streaming, I use spotify to stream for new music, not for serious listening.

We now have a Frontier9472 Network modum/router installed. It affords WiFI and has 4 ethernet and 1 USB output. I am looking for a streamer that can receive signal via any of these outputs and serve Qobuz. The Bluesound Node 2i seems a likely candidate as I will use streaming for music exploration and background listening. I will play the Node into my Audio Mirror DAC. 

I have 2 questions)

1) are there other streamers available that would serve my purposes that are around the Node price point? 
2)  Would a ethernet or USB connect best the Wifi for SQ?  I know there are other threads on this, some quite lengthy describing ways to improve over ethernet. I just want to use either WiFI or a cable.

As I explore the merits of streaming I will likely upgrade my approach.

I love tmy P-J S Ultra but it is no where near the price point and slightly more difficult with fewer options and crappier art than BluSound.
Don’t even try SGC fendi unless you are paying for Roon. Even those idiots could not get it to work for me.
If you are looking at Aurallic, iOS control app only. But I guess you are OK there.
For the P-J S Ultra use the BubbleUPnP app for betters o/l sorting and art on Volumio.
@mesch For your stated purpose, i.e. background listening, Node 2i with direct ethernet is your best bet. I use it with my AMT3 (non-SE) DAC, and it works very well. I love the radio function (Radio Paradise) that comes with the Node.

BTW, at one point you were looking to purchase a Raven Audio Blackhawk. Did you end up getting it? Just curious.
On one system I use a simple Raspberry Pi. If you go with a zero it can be really cheap. Not sure how budget you want to go but I drive this with Volumio and am extremely pleased with this feeding either a dac hat or my stand alone. Again, this is bargain basement $ with pretty solid performance. 
 I have decided I will go with the Bluesound Node 2i and use a quality ethernet cable from the router. based on what I have gathered from this forum it is relatively user friendly, quality at a budget, simple installation, and will serve my current objectives. Should I find that streaming replaces my current listening mode (CDs) I will likely upgrade and use the Node in a secondary system. 
I thank all for the guidance. 

@arafiq Yes I have been playing around with the idea of going back to a integrated amplifier. The Blackhawk was (remains) one of interest. Not sure what I am going to do at this point. I did purchase a Line Magnetic 211ia which I am playing around with. Just missed a opportunity to purchase a Sugen A21 SS integrated I wanted to try out. If one buys right one can explore aspects of audio in one's own room/system and resale for little loss. Some risk involved however I feel it a small price for the education. It is a hobby after all. 
I use the Allo USBridge to great success. It’s an Ethernet-to-USB Bridge, works as a Roon endpoint. Pretty simple and affordable.
