Regarding your latter comments. Yes, for the past 3'ish years I have been slowly saving for a tractor on top of all of my other expenses, retirement savings, etc. , while looking at an unhealthy amount of tractor ****. I have enough saved up for ~70% of the total tractor cost.
My problem in all of this is that I come from a long line of <ahem> ... let's say, "spendthrifts". Aside from purchasing a home, I have never been in debt a day in my life. This has allowed me to be in a stable financial situation where I am on track for a comfortable retirement, have liquid emergency savings if something catastrophic happens, and can still put aside some each month for items such as a tractor.
However, living this way for many years makes the thought of taking out a loan a very difficult pill to swallow; even if what I really need right now is time, rather than money, and in the grand scheme of things the financial "loss" would not be all that great.
I'm not one to make rash decisions, but instead prefer to think something completely through and try to see all of the angles. However, I also realize that my way of looking at it purely as an economic exercise does not necessarily paint a complete picture of the decision making process. For this reason, it's very helpful to hear how others came to their decision, as it helps me to consider variables/considerations I may be overlooking.
