Hi to everybody out there.
I'm a saxophone and guitar italian player wanting to enter the world of MIDI keyboards.
As a first try I have about 500US$ to spend.
Well I've been considering both new and used keyboards, but I've found no uninterested suggestion on which one to buy.
The thing I want are : GOOD sounds (no digital sounding piano and similar stuff: as an acoustic player I'm poorly interested in Synth sounds and complex routines of manipulation, very interested in sound quality), a disk drive, a nice screen, 60 full size keys, possibly an AUDIO IN jack and some AUDIO out jacks.
The models I'm thinking of are:
Casio 731/811 (320 US$) nice look, poor sound
Roland EM-50 (500 US$) very good sounds, poor look
Farfisa tk84 (330 US$) poor look, poor sound
Yamaha PSR 540/640 both medium look, good sounds, difficult to manage velocity

In the range of used models:
Yamaha PSR-6000 (500US$)
nice look, don't know sounds
Korg i5 (500 US$) great sounds and arranger, poor screen, look, INs and OUTs
Technics KN2000 and 1000 (500 and 250 US$)
Roland E70 (250US$) nice sounds, good amplification, no disk drive
Various CASIO.

Can anybody help me, or suggest me to look for something else. I can wait the good occasion!

Hope to hearing from you all soon.
Bye
