They are in nice shape except for one thing. Whoever "professionally" refoamed the woofers used the wrong replacement dust caps (or installed them backward). That lack of attention to detail would drive me nuts, and I can't tell for sure from the photos, but it also makes me wonder if the replacement foams are the correct ones and if they are properly installed. If you're going to be asking top dollar for a speaker that is not exceptionally rare, it had better be 100% uncompromised. To me, since I am used to seeing the correct concave dust caps, those incorrect convex ones just look so wrong to me.
Like the L100 Century before it, prices on the L36 Decades have been creeping up. When I restored mine about a year and a half ago, clean pairs were going for $300, with ones in average condition fetching $250/pair. Of course, two years ago you could still get a decent pair of L100s for $500. Now $700 - $800 seems to be the norm, and I've seen asking prices of $1000/pair for properly restored samples. Now, $400 seems to be the going rate for a clean pair of L36 Decades, with typical asking prices for a pair in average condition in the $300 - $350 range.
All that said, no way would I take $400 for my L36 Decades. I was actually offered $500 for them and turned it down even though I know that is above market value. Mine are a one of a kind pair that were meticulously restored inside and out. Actually, restored isn't even the right term as mine look nothing like they did originally. I also how much time and money went into making mine look and sound the way they do. Plus, there is some sentimental value there that you can't put a price on. I'm rather fond of mind and had no intention to sell them when I started my restoration.
In any case, even though the asking price is $400, that doesn't mean you need to pay that. If anyone is interested, and not as offended as I am by the incorrectness of the woofer dust caps, you always offer less and use that as a negotiating point (just make sure the replacement foams are properly affixed to the rear of the woofer cones).
