Does your collection have a salary cap?

[Doug]

I was listening to Dave Ramsey's radio show (a financial guy if you haven't heard of him) a few weeks ago and a caller asked him how much was reasonable to have invested in collectibles. His answer was no more than 10% of a year's take home pay, so for example if you take home $35k a year, you shouldn't have more than $3500 tied up in your collection. It reminded me of a teacher I had that collected low grade 1933 Goudey commons and he had a strict maximum of $50 per card. I also have another friend that sticks to the total value limit, but doesn't have a specific limit per card. If he hits his limit he has to sell something of equal or greater value before he buys a different card. This got me to wondering, does anyone on here go by either of these methods or a combination of the two? That and it seemed like an interesting idea for a poll...
