Vintage Synth Repair

I currently own a Farfisa Compact DeLuxe and a Workstation WK6 from 
GeneralMusic.I play the organ for "The Frantic Five" 
(http://www.geocities.com/franticv)

i wanna get a hammond or hammond-like organ as well and thats where 
i d like your help and recommendations.

I dont think i can afford or be dedicated to carry around an 
original Hammond monster organ as B3 or an alike of it. So i have to 
buy something that sounds like it but without the bulk and the 
weight.

After a lil research i think i should choose something between 
Hammond XK-2,Hammond XK-3,KORG CX3,Roland VK8.(i m also interested 
in buying a Fender Contempo Organ or a Vox Continental by the 
way :P) 

Could you plz gimme a short list of pros and cons of each one of it 
wether you ve played on it or just what you ve heard from 
friends/musicians.If you could post some links/urls would be great!

As for what i want or have in mind,here it is: 

-i want it portable
-fat,rich sound but i would apreciate it if i could reproduce sounds 
like Vox organs or the cheesy farfsa 60's pop sounds
-i play (or i wanna play in the near future) 60s 
garage,blues,soul&funk,rock,acid jazz in their vintage eras of 
course.
-i dont wanna purchase another "hot" synthesizer but a vintage combo 
organ so i dont care about other bank sounds like strings,pianos
(eeewwww gross!) etc nor for rythm or percussions so bother telling 
me about them.Im a vintage enthusiast so bring it to me!
-nice price(i would buy a pre-used , no problem it it plays ok)
-try to describe and notify me of teh differences 
concerning,sounds,effects,rotary,leslie,which one co-operates best 
with leslie speakers or leslie-like imitations speaker 
systems,feeling of the keys(heavy,hard,deep,shallow etc)
-if anyone sells his own mail me :P (organus@...)
