Why so many used focals?


I look on the forums to read and learn about owners reactions about focals and compared to many brands there's little action which would make me think it's a small company... til I search on AG for used focal speakers and pages of used speakers come up! Are they the type of speakers that offer a clear upgrade path OR are they short term speakers that wow the listener early and fatigue in the long term?

I couldn't be in the same room with focal's from the 90's, but the recent speakers have been very pleasing to the ear in auditions. Experienced reply's would be appreciated and please no hating on the brand. Tks

For the most part the conversation was helpful with only a few cheap shots. I have a room that made a pair of salon2's sound lean with 250 wpc so i'm opting for the kanta'3 with the bigger box and drivers, not for the deeper bass since most of what I listen to doesn't have much if any energy below 40 hz and I want spl! My question was legit because I was so impressed with the speakers at the store, but it usually takes me a bit more time than a typical dealer's going to want a pair of speakers out of his shop. I've been buying and selling used hoping the next one will be the last, but it's a slow process and even with reselling it costs money, not thousands but hundreds and it add's up. I have to sell the salons b4 I buy the kanta's and my dealer will let me take home his floor demos first, but since i'm going to work him on the price I want to do as much of my own leg work as i can first, and if i'm buying new i have to get it right.
There's an old saying in engineering Steve, "If it looks right -  it usually is".The Kanta 3's look right. I don't know why, but rear ported speakers are a game breaker for me. The Kanta 3's are front ported, and look at these numbers. Sensitivity 91dBFrequency Response (+/-3dB) 33Hz - 40kHzLow Frequency Point 26HzNominal Impedance 8 Ohms26Hz pretty much gets any job done, 91db with a nominal Impedance of 8 Ohms .... so they're not that hard to drive, two 8" drivers give them good weight, an inert cabinet, and they're decoupled from the room because of the speaker stands; I'd say you have the foundations of a speaker here that should give you many a year of listening nervana - - - at least on paper. (Mind you the proof in the pudding is in the actual listening).You're right to take your time .... they'll be making them for awhile.
I'll check but I think they're ported front and back. I couldn't pass on a pair of Usher BE-20 DMD Dancers that came up locally and am really having fun with them. It never ceases to amaze me how much impact a room can have on sound. I had a pair of R 107/2's down here, the ones with 2 10" woofers inside the box eq'd to be flat to 20 hz and vented out the top, even those speakers loaded my room with decent bass tho' overall the tweeters turned out to be a little bright for my taste. I have no engineering background or prejudice to speaker design just what works in my room. 
^ Good find. Rest assured you chose well - much better speakers than what Focal produces at that price point.

Any speaker engineer worth his/her salt knows that a front port is more likely to produce audible port noise when playing near its limits. 
Thanks helomech, the seller said his inbox exploded when he listed them and I was the first to offer pick up with cash in hand, after last nights listening session I believe him. I still want to hear the dyn C60 and Kanta 3 down here but i'm not in such a hurry now. Thanks for everyone's contributions.
