Probably true in most circumstances. I have to consider what the delay means for getting jobs done that need to be done now or at least soon. Paying someone is one option. Renting equipment is another. In the end both leave me with a job done but nothing to use for future projects or simply resell. Now, buying an 'inferior' product, which is a subjective determination, would allow me to get the job done sooner and I would have a piece of equipment I can continue to use until the 'premium' equipment comes in. Once that happens I can resell the current equipment. I won't get the same price as new but the work I get done is going to be worth more than what I will lose out when reselling. Of course I could end up beating the crap out of my 'inferior' product where no one wants to buy it but I suspect there is always someone with the resources to restore it to a condition that meets their needs.
I guess you couyld also argue that I could just keep it and use it for those projects that have a high likelihood of damaging the equipment and just use the 'premium' product for regular safe use.
