Compact Kegorator Advice

Ok, so I have decided to build my own kegerator and lucked out, greatly, by finding a 4.4 sized fridge at home depo. That said, I'm about to order my conversion kits, but I do not comprehend completely which ones to buy and what the difference is.

So, if I read this correctly, the difference between the first two are "Premium Pro Series Two Product Double Gauge Regulator" vs "Economy Double Gauge Two Product CO2 Regulator". Is there a difference between the two?

The second one seems to be just the deluxe kit minus the drip tray.

Also, none of the videos I watched or instructions I've watched said anything about cleaning kits. Is this something worth picking up or can the lines be washed with just soap and water, or are these items worth picking up to keep beer quality high?

Finally, which CO2 would be fitting generally for a compact Kegerator? Is a 10 too big, or would a 5 work fine?

Any advice is appropriated. Prost!

 

the upgraded regulator has a manual relief valve, which is a nice upgrade. That said i had the same regulator, it broke. Just saying. the economy one i have is still going.

the 5 pound tank will fit better.

also those are sanke taps, if you are kegging your own you will want the homebrew conversion kit. if you are getting commercial kegs you will want to make sure you have enough clearance with the taps. they get pretty tall and usually are taller than a standard mini fridge like that.
