Used yamaha u1 or yamaha u3???

[chfsin]

Hi,
I am in Singapore and am looking around for a used piano for my daughter who has just learnt a few months. Saw a used yamaha u3 serial number 245xxxx which costs Sgd2800 dark mahogany colour which includes moving n tuning n 3 years warranty. This is from a company that buys n sells used pianos.

The other is a used yamaha u1 serial number 418xxxx which also costs sgd2800 glossy black, but excluded moving n tuning. This is from a home owner.

Which do u think I should pick?

Thanks!
