Is that so David? It's always nice to hear how people started the piano and where they grew up. Maybe I'm odd for saying that, but hey that's me.
Do you by any chance know what an 'ocassions' piano is?
Here is a whole list of Yamaha's uprights I could afford (well only the U3 probably).
https://www.vanurk.nl/producten/Piano/Occassion/Yamaha/4000When I visit the store friday, I'll definitely check those out. I'm surprised the U3's go for that amount, I really thought they would go for 10k+ USD (they're about 7k usd at that store).
I've checked the website out, and I believe these are used pianos, but restorated very well. Even to the point of giving warranty (10 years for occasion and 20 years for grand) 0.o. This is what the list says:
- The entire cabinet is equipped with a new black high gloss polyester lacquer.
- The soundboard is repainted.
- All spindles (nuclear markers) in the mechanism are replaced.
- Comb inspection for cracks or separation.
- Strings sound inspection and corrosion.
- Hammer felt shapes and intonation.
- Hammer regulation.
- Under the Hammer and opstoter spring inspection.
- Hairstyles renewed.
- Draft regulation.
- Complete new keytops.
- Pedals check and adjustment.
- Rast inspection for swelling or dehydration.
- Sounding board inspection for cracks or climatic stress.
- Voice control block voting strength and or dehydration.
- Rim timber inspection HINTS stress.
- Hinges and pedals are fully polished and are therefore as'' new''.
- Hinges are checked for smoothness and beeps.
- Keyboard inspection for cracks and warpage.
(I translated from google translate, couldn't translate it myself beacuse I don't know the correct terms.)
Is it legit? I am not able to believe they would ripp me off. But it is indeed the U series of Yamaha you suggested. Maybe I could even bargain the U3 for 2000 euros with payment plan, not sure 0.o.
Once again David, God bless you and thanks for your help!

Edit:
Found an affordable new Kawai : K-15 E
https://www.vanurk.nl/product/16Google translate:
The Kawai K-15 E is the lowest piano from the famous K-series. With its height of 110 cm, he has a surprisingly full and bright sound and is an excellent piano for people who have less space, but still a good piano to own. Due to its attractive price, it is also a good starter piano and is therefore much by piano teachers recommended. Here are some specifications
Meassurements in cm: (HxBxD) 110 x 149 x 59
Weight: 196 kg
So this one is not secondhand or anything. Do you have an opinion about this piano David? Your opinion on the U series (the occasions piano's) is just as important!
