Possibly buying a kegerator - need advice

I have been planning a keezer build for a while.  What I had sketched in my head was a 4-tap kegerator built on about a 14.8 cu. ft. chest freezer - pretty standard stuff…  However, today on Craiglist, I found this:

It has a badge on it that says “Superior Mfg. Co.”  I think this is a Bev-Air that Superior badged over, but I could be wrong.  The seller doesn’t really know how old it is - bought second or third hand.  He says it runs great and is in working order.  He is asking $1700 with the tap handles, CO2 tank and regulator included.  I know that new, these retail for $3000+.  I figure with the parts needed to convert it to corny kegs, I’m coming out even or a little cheaper than if I build it myself.  I am saving myself the build time.  I mainly concerned if it might be too old and how I am going to get this bear down to my basement.  Thoughts??  Thanks in advance!

With something that nice I’d stick to my motto of “Don’t think, just buy.” What material is the top made of?

It is a regular commercial grade kegerator - so a galvanized steel box with vinyl covering and a stainless steel top.  I know it looks nice.  As for the age, I’m sure these commercial grade kegerators can run a long time.  Just thinking of how I’m going to move it…

Commercial pumps, while longer lasting, are much louder than a residential freezer or fridge. Might be something to consider depending on where you want to put it.

I hadn’t thought of that - good point.  It’s going to be in the basement…which will one day be my basement bar, so I am not overly concerned by that. I’m thinking of paying a mover to get around the moving problem.  I think I might be talking myself into it.  I’m just thinking a commercial unit might be over-kill.
