Yes, there is a bit of ... well, I was going to say, a dark art to loading photos with the site's utility. Let me say instead, "It has a bit of personality." Not a great deal; you can make friends easily enough if you follow the instructions blindly.
$2500 may not be quite enough to retire on, but I wouldn't cross the street to avoid the sale.
"My local piano dealer says that the cabinet needs refinishing. (It has some dullness, dings and a few scratches. The brass hinges and pedals are also dull looking)."
Fine. So, get some Brasso and polish the pedals and hinges up; get whatever product is right for the case and give it a little rub-a-dub (Cory has a product; you can buy it here from http://pianosupplies.com
which is PW's sister site, or your tech probably can get it for you). I could say the same for the keys; my piano manufacturer says use Windex, sprayed gingerly on the cloth, not the keys. Your pianomaker, or Cory, may say something different. Whatever; just clean it up and have it looking and sounding its best. Have the tech in to give it a nice fresh tuning and spruce up the inside of the case. As I have found too many times, you never get a second chance to make a bad first impression.
Where to list. Ask your tech. You can buy a classified ad here. There are websites. Try to list it where it will maximize a realistic target audience and minimize exposure to creepy "types." Daily newspaper classified ads will get you some calls from dealers who like to pick up pianos after someone dies or moves, or doesn't want to sell it themself. If they will meet your price, that may be good enough; they will expect to charge twice that in the store after they blow the dust out of the case with a leaf-blower. As regards price, they are bottom-feeders; don't lose your smile over it. In fact, without taking out any ads at all, you could drop in at dealerships which sell used pianos and see if they're interested, and look at what they have on the sales floor, for what price. Just keep a grip on yourself, as you try some new pianos. It is like staying out in the sun too long without sunscreen--- a few minutes may give you some color in your cheeks, but a few more may get your bald spot burned, your cheeks as red as those older ladies who lay on the rouge, and your nose peeling badly.
But stop the presses--- if you are buying a new piano, they may be willing to make you an offer on the old one, as a trade-up. Or your tech may know someone who is in the market. Or, other techs may. You can find piano technicians in your area from http://ptg.org
Piano Technicians' Guild.
Best of luck! And BTW--- what are you getting as your new love?
