$1100 dollar budget, I need a keyboard

[thedude400]

I'm in the market for a new keyboard. A 1998 Ensoniq keyboard is the extent of what I have owned so I'm a bit of an amateur. I prefer to record a realtime bass guitar and will be doing all my drum tracks acoustically so drums and bass aren't really of interest to me. Basically what I will be needing from a keyboard is this:
-at least 76 keys (can compromise if i find a reason to)
-A few good piano's
-some good organs
-a good versatile range of strings
-a lot of cool synths
-weighted hammer action keys (can compromise to semi weighted If i find something that meets the rest of the standards well)

I have been to guitar center and tried the motif, triton, and phantom and though I like them all I'm not sure if a sampling/workstation is what I'm needing right now partly because I'm not exactly sure how to use them and just how useful they really are. Not to mention many of the standard workstations are out of my budget anyway (unless I buy a 61-key and used) ALTHOUGH,there is a good chance I will wish to learn these within the next few months. I don't want to buy simply a synthesizer and regret not getting a sampler/workstation. My budget is up to about 1100 dollars and I will buy used. In fact I sort of plan on buying used.

I've narrowed it down to these following units:
Yamaha S90 88-key synth
Alesis Q8.2
Roland XV-88
Yamaha Motif? (used 61-key)

I really have my eye on the XV-88.I have yet to look too much at kurzweil's because they seem rather expensive but I am up for suggestions.

If anyone has experience with these chosen keyboards and could suggest one to purchase in accordance with the given requirements that would be helpful.
