I find the soft pedal fairly useless on well maintained pianos like the Sohmer, Baldwin, Howard, Wurlitzer (pre globalization) and Steinway consoles I play. The middle pedal could be useful, but the function varies so much between brands and models that it is best not to get used to using it. I took a lesson on a modern Yamaha 2 years ago, the middle pedal was some kind of felt damper that touched all the strings - talk about useless!
However, take a walk down to Salvation Army or St Vincent de Paul resale shop, and see if you can't find a $50 piano that is much better than a piece of plastic with rubber keys that will be trash in 10 years. I picked up a nice playing Wurli spinette last month for $50, with a smashed music stand, cover pulls missing, and various dents and scratches. The tone was dull and boring but the mechanism was consistent enough that I can practice this summer in my camp on it (caravan) without losing technique due to a three month layoff. And for $50 it was in tune! probably because it had a 3" x 6" solid pin block, a trade off of stable tuning for boring tone.
Or for $100 around here, you can get a Baldwin Acrosonic spinnette with a beautiful tone, although not as fast as the 40" Baldwin consoles that draw more like $600 and get hauled 70 miles away by some flipper in the country (which costs another $170 by U-haul truck, how I got the Wurli home)
Do not be tempted by post-globalization trash. I played a nineties "Wurlitzer" in a student's home 2 years ago, the action was so inconsistent you couldn't play soft at all without dropping notes, either with or without the left pedal.
Have fun whatever you do.
