The same applies to pen. Some don't understand my I spent quite a bit on a fountain pen when I could get dozens of ball pen for under $5 at WalMart.
so true, I went thru a similar fountain pen phase (and similarly it too tapered down once I had decided on one or two nice models that were right for me, but it took about 6 months of trying them out (and reselling them afterwards, lol).
I didnt go totally nuts or anything (there's no real upper ceiling on prices with fountain pens, lol). It began because my grandfather left me a shaeffer snorkel. And let me tell you, even if you're not into pens (and I wasnt at the time), the snorkel will make a believer out of you.
Its so mechanically complicated that its like something out of a disney movie (think the inventer guy in chitti chitti bang bang). A real fun gadget - and wrote like a dream, like nothing out there writes today. (I like stiff nibs and with the one on this, you could kill someone pretty easily, lol).
So it all began with me trying to fix it (refill mechanism worked but wasnt taking in much ink). And I discovered the *vast underworld* that is the pen-lovers world out there. Its a much bigger world than keyboard lovers but its just as secretive and hidden, in alleyways and side streets and niche corners of the web where these folk congregate, lol. And they were amazingly helpful to me in trying to understand how the damned pen worked (very complicated! and really really neat if youre a gear head) and fix it up.
I still have it though I dont use it anymore. After some comparison shopping (thanks, ebay!) I settled on a low/mid-level parker vendome/rialto which works well for me. Not that I write with a pen that much, but its "nice to have". Not pricey at all but love the way it writes.
But there too, once I figured out what I like and dont like, I moved on to the next comparison shopping event (which was keyboards, lol). I did the same with my desk, chair, monitor stand and setup, etc - the advantage is not only inspiration as you say, but true efficiency I think.
It really is efficient to have a set up that you like and that is second nature to you, when you sit down to work. (The danger is that the search for that perfection can sometimes be an excuse to procrastinate of course!). But you know, its better than taking up a drug habit or something, lol.
