Understood.
I still plan to go ahead with this, but want to stress that I absolutely respect the rationales offered above. But where they are driven by necessary commercial/time considerations, I'm not so constrained; if I have the time available to invest so I can put my limited cash elsewhere (my eye's on a Supercat 20 in Texas at the moment), that's what I'm going to do. But the time/money equation isn't the only thing driving me, either. As the old Stiff Records slogan goes, "Try everything once, except incest and folk dancing". I haven't yet pulled apart an EZ30, I know that I'm going to learn some new stuff, and if that includes, "They were right, this is stupid, I wish I hadn't done it, and it's time to buy a JDM", I can accept that outcome too.
