I asked myself this same question in 1996. I am competent on both drumset and bass. I had basically quit playing drums (at least I was not going to join any band as a drummer), sold my kit and started buying nice bass stuff (Trace Elliot rig, custom-built jazz-style bass). I decided I wanted a 5 string and went to NAMM to look at all that I could. I didn't find "the one" so I was just about ready to have a 5 string built that would match the 4 string custom jazz. THen I wandered into Guitar Center and played a Zon. It instantly spoke to me, and was clearly the best bass I'd ever played. However, it was about $2700, and I had a hard time justifying that. Here I am, just a dude playing covers in bars...why am I even thinking of dropping that kind of cash on a bass? Well, I went home and explained it to my wife (not yet married at the time). Her questions were quite simple: "Well, do you like it?" My answer was to the effect of, "Of course I like it. It's the best feeling and sounding bass i've ever played." "Well, if you like it, go get it." I tried rationalizing that I was "undeserving" and "didn't need anything that nice", etc etc. She convinced me to do it and I thank my lucky stars every time I play that bass. It quickly became my "#1" and has stayed there for over 20 years.
Just do it.
