I've seen some consoles around here go for $200. I'm talking 44' "studio" models from 1955, not feeble slow 33" spinets. Case damage is always good, my 1941 Steinway has lead car wheel tracks all over the kick board and a big piece of veneer missing. Doesn't affect the sound, just the price, and drives the instant-on resellers away.
Brands to go check out, 39" to 44" tall, Sohmer, Steinway, Baldwin, Wurlitzer, Everett, Mason & Hamlin, Chickering. Most of these brands have been purchased and pasted on modern import junk, so limit these brands to 1977 and earlier models. Brands that are junk, Kimble, Winter.
Frankly, for home use I prefer a console. Baby grands have shorter bass strings and project up, not at the player. Check hammer wear, both felt dent and shaft wiggle. Check for mold, mouse chew spots, broken soundboard, uneven damper action. check the hammers move, and speed of repetition is good. Most of all check the sound, but don't be annoyed by tuning problems, if you want a bargain. Find a key that has the 2 or three strings in tune. Listen to the split between 2 and 3 string notes- my Mother's 1947 Everett did this badly but they had this corrected by the 1982 model I auditioned.
If you like honky tonk or ragtime, actual pre-depression upright pianos are a lot of fun. They have a different tone, one that is missing from any modern piano. This tone is reproduced in some electric keyboards, but any electric lacks the singing with itself of a stringed piano with the dampers up. Uprights run 600 lb up, so take a competent dolly with 4" wheels (New Haven or Mcmaster.com) and three hefty friends. Uprights are so hard to move, they are usually free or $50. There were too many competent upright brands to list, just go take a listen. Some of this era were also junk, like my Grandmother's.
