2 vs 3 faucet draft tower

[Oktoberfest]

I am about to purchase a 2 or 3 faucet draft tower. My problem is my kegerator will only hold 2 cornys max at 1 time so I will always have 1 open spout not being used. I've learned over time in homebrewing to go big or go home. I have bought equipment and a year later wish I had spent a few extra dollars and gone bigger. So, I guess my question is, am I an idiot for going for the 3 faucet in this scenario? I am thinking longterm and perhaps I could use the tower down the road in another application. The difference in cost is $35 which is easily doable. Only downside is perhaps lack of airflow in the tower do to lack of air space with the additional line. Any suggestions are appreciated as I'm unable to think for myself today.

Right now, I have a two tap tower because I can only fit two kegs in the fridge. When this fridge dies, I'll likely move to a bigger model with more taps through the door. It would be nice to be able to age/condition more then two kegs in the fridge. When I do move to a larger fridge, the set up obviously won't use the tower. The tower will be sold or given away.

I guess it depends on what you have planned in the future. If you plan on getting a smaller fridge or chest freezer that can hold 3 or more kegs AND use the tower, I'd go for it. If that's not the plan, buying the third tap now seems like a waste to me.
