Nah. I couldn't justify that on my car. Lenses last a lifetime so I don't mind spending a bit extra for the top shelf items and they hold value really well too, not that I'll be selling anytime soon. I don't really need much more now. The only big $ items I could see myself getting at some stage would be a strobe setup more powerful than my speedlites and a camera body update. I don't think it's an unusual amount of money. I'm sure most of these guys have spent more than that on their cars, jet skis, motor bikes, boats etc etc. If it makes you happy and your priorities are taken care of first then I say go for it!
