Well, from an investment standpoint, Albert's locker setup there is supposed to go for somewhere between $2,000 & $3,000. If I got it for $3k, I think I'd be able to pay it off in about 2 years. At 8% interest on the card, the total cost would be under $3,500 assuming I only paid off the interest each month.
Let's say I wanted to sell it in about 20 years. At 3% straight-line inflation, I'd need to be able to sell it for ~$6,300. I think that's extremely doable. I have a feeling this would be worth more than that once he retires.
Ah, but this is crazy-talk. I don't even have anywhere secure that I could keep such an item like this, and it's certainly not staying in my house so my cats could jump on it.
