Guys, I`m a desperate need of help. I`d rather this was replied to soon... Thanks...

I`m thinking of getting myself a piano.
It`ll be second-hand, since I want to get something good with a mellow sound, and NEW good pianos with mellow sound usually cost a big lot...
So here`s the choice I have (what I got after flicking through a "buy and sell" magazine):
a) Nocturno - unknown price (says it`s not expensive)
b) Petroff - $1000
c) Weinbach - unknown price
d) Alexander Herrmann - $888
e) Becker - unknown price
f) Cherny - around $170
g) E. Schuster - $200

So guys, what would be the best bargain out of the lot?
I realise that Petroff has the loudest and proudest name of them all, but I don`t know... Famous doesn`t always equal best.
Please, guys... I really need help with this, seeing as I am not an expert on pianos.
Much obliged...
Cheers, Olga.
Also, if anyone has anything special (whatever details you might think of, I don`t know) to add, or anything (hey, you never know), my e-mail is stargirl_y@yahoo.com
Thanks...

BTW... I`m incredibly sorry this has been posted in more than one forum, but I`m desperate and I need it QUICK, since these offers won`t be around for long.
