Here are a few ideas:
1. Read the reviews. One guy complained about the faucets sticking, which suggests the faucets aren't that good. You'd want forward-sealing faucets; I suspect these are not.
2. The instructions apparently aren't that great.
3. It seems to come with everything but the kegs...the detailed description says it comes with "an" American Sankey coupler...that implies only one sanke connector. You'd need two if you plan on using two kegs.
4. And that means you'd need sankey kegs. You can switch that to ball-lock connectors if you're using corny kegs, just be aware that you'd have to do that.
5. Casters are optional, which I presume means extra cost. I'd want those.
6. I don't see any gas lines included in the inside pic. I'd make sure all the lines are there. If you're buying a complete setup, it should be....complete.
7. I don't see any way they're cooling the tower. If not, you're going to get foamy beer to start as the beer passes through warm lines and warm faucets. When beer warms, it releases CO2 from solution....e.g., foam. If there's not some way of blowing cold air up into the tower, I think that would be a dealbreaker for me.
Anyway, those are some thoughts. FWIW, if the footprint is part of the issue, you can build a keezer out of a 5.0-cu-ft freezer, with a slightly larger footprint, but you could make it with exactly the faucets and fittings and such that you wanted. It would costa little less, too. You could put Intertap flow-control faucets on that, use stainless shanks and fittings, and do that for under $150 including tubing, fittings, and all-stainless steel. The freezer would cost about $160, an Inkbird controller for temp $35, a new 5-pound CO2 tank about $70, a Taprite 2-gauge regulator for about $50. T-splitter for the gas, about $2. Wood and tape and finish for the collar, maybe $50. You'd have to figure out a drip tray for it.
Now, that actually is pretty close in price to the kegerator, but the parts are better (the faucets are stainless, the shanks and tailpieces too), and if you go up to a 7-cu-ft freezer, you'd have room for 4 kegs for not much more in cost than the faucets. (Just sayin').
Just to show what you could do if you make your own, here's a pic of mine, complete with glass rinser (run off a small keg filled with water inside the keezer). That's a 9-cu-ft freezer, I can get six kegs in there.
