Old enough for a wine fridge?

I read in a book once that you do not need a wine rack until you are 30, as you can't normally afford enough bottles to fill it up. And if you do happen to buy enough bottles to go on the wine-rack you are likely to drink them all in one go anyway.

So, at 40, am I old enough for a 34-bottle wine fridge? I am not sure. I can afford to buy enough bottles to fill it up with, but it is quite clear that if you have the bottles at home - you drink them rather quickly.

I have been experimenting with "Cleanskins". Cleanskins are according to Wikipedia:

In Australia, cleanskin wine is a term for bottled wine that does not carry a label or any other identifying marks. Cleanskin wines are sold in sealed cartons of six or twelve bottles and the carton must display a label that meets the minimum legal requirements as defined by Australian law.
Cleanskin wines have been sold in Australia since at least the early 1960's but are generally only popular during periods of imbalance in the Australian domestic wine market. Wineries will sell cleanskins to dump excess or unwanted wine stocks and do so to avoid the negative consequences of discounting their existing brands. This form of dumping often has very little to do with the quality of the wine and consumers can benefit greatly however there is always an element of risk when purchasing cleanskins.

Basically it only states the grape and sometimes the region. Never what winery it is from. We have this huge discount bottle shop close to where we live, so went over there and bought 2 bottles of each one of them. I have now found some I like, like "Chardonnay AP2" and buy them in cases of 12 for $45 or so. Not bad, but they will probably be changed for something else shortly and I have to re-do the exercise.
