As a retailer of bookbinding tools, I cannot recommend too highly the fantastically excellent advice of Carl Richards. In his NY Times article, “The Financial Benefits of Buying What You Love“, he lays out a strong case for buying what you really want, rather than settling for a cheaper option. It is not too much different than the old adage, “Buy the best tools you can afford”.
Seriously, though, I think almost every time I have not heeded this advice for a variety of rationalizations — the tool is too expensive, I’m not going to use it that much, I don’t need something that good, etc… — I have regretted it.
As his napkin illustration summarizes: you buy it, you love it, and you keep it. And even if you fall out of love, you still have something of value to resell, rather than more garbage.
