Thanks everyone. The serial# is 591073. Likely only a few years old by my estimation.
Yes, the price seems very good (new puchase price was $16,000), but recent home renos have drained my account so I wanted to make sure Petrof still made good pianos (it's been 20 years since I played one).
Someone suggested I look at digital pianos, due to my family situation (can't make noise when kids are sleeping). I'm thinking about a Yamaha NU1, but am wondering if I'd always regret letting that Pertof slip through my fingers.
The serial number confirms your estimation. I would still get it inspected though before purchase.
The choice of a digital or acoustic in your situation is a very personal one. It depends on your comfort level with technology and the layout of your home.
The P125 G1 has a middle pedal that Petrof refers to as a moderator rail. Felt is suspended from the rail and quiets the hammer strike when the pedal is applied and the rail is in place. As practice rails go, Petrof's is okay, but it does affect the feel of the action and the sound produced could still interfere with kids sleeping if their bedroom is nearby. Activating the rail will certainly decrease your enjoyment of the playing experience, but it may be an acceptable compromise to you, especially if you don't need to employ it often.
The NU-1 is a very compact piano (if that's important). It has a Yamaha acoustic upright action stuffed inside. The action feel is good. Yamaha also offers the N-1. Its cabinet is a little unconventional because Yamaha stuffs a grand action into it, so the cabinet requires more depth. It's more expensive.
If you are comfortable wearing headphones while playig, either of these hybrids will give you an enjoyable playing experience. You will not worry about disturbing anyone's sleep. Headphone play also allows your practice sessions to be more self-critical and analytical (if that appeals to you).
The sound sample you will hear from either of these hybrids is from a Yamaha concert grand. It's important that you like that sample because you can't escape it without adding other hardware.
The big advantage of the Petrof (or any good
acoustic) is the natural emission of the natural sound. When you can play without volume constraints, you will fully appreciate the lovely tone of the Petrof. The Yamaha NU-1 will transmit a signal rather than emit a sound, and it will transmit that signal through a pair of six-inch speakers. The result will in no way compare with the remarkable sound quality you will get from the same piano through excellent headphones and will in no way compare with the natural sound of the Petrof.
To sum it up, both the Yamaha and the NU-1 excel in their areas of strength. The Petrof's strength is to fill a natural listening environment with beautiful sound. The Yamaha's is to offer a good facsimile of acoustic piano playing in a very small box at a relatively low price. It also has the advantage of interconnectivity (e.g. headphones, direct recording) if that appeals to you.
If it were me, I'd get the Petrof inspected and buy it if it checks out. It's a good long-range solution for a dedicated pianist. I'd also buy a good stage piano in the $1000 or $1500 range and some excellent headphones for silent play. Since advances in digitals and hybrids are coming with a rush these days (the NU-1 was introduced just a few months ago), it might not be prudent to sink your whole piano budget into a current model.
