Yes, this dude is way OCD, but you know exactly what you're buying and as anal as he is about his ad, you have to believe he takes care of his gear.
Guess I'll be the lone dissenter here, but I'd rather have an ad like this that offers way too much info than the online sellers who put redundant info in the description (essentially repeating item make, model & price). Or worse, the seller who doesn't know what he's selling, how it works or IF it works - but he's SURE it's an easy fix and is worth $$$$'s once it's working because it's "rare". In my experience, calling clueless sellers is a complete waste of time and negotiating with them is worse. They admit they know nothing about the gear they're trying to sell, other than Uncle Fred says it's worth thousands and you're only offering $225...
Give me OCD dude any day...
