Cheers Jason will check that out tonight can’t see Youtube in work 
VSTi - Kontakt! Closest to analog sound you will get. Pick your libraries wisely…
VST - Nebula - by far the best for eq, tube pres, and tape but a little buggy for live use but for production…forgetaboutit!
Sony Oxfords - Limiter and Inflator rock
Stillwell - Everything
Ohm - everything
Maybe ive said too much…lol
No prob, a few of the Top ten have already been mentioned in here (ie Massive, Albino)
Massive really is one you should get into. Once you get a hang of it the sounds you can produce are beyond amazing. FM8 is another one I like as well.
urs is good.. u-he, spectrasonics trillian, overloud th1, anything ssl, their xverb is pretty good, stillwell, oxford (love using their dymanic channel (so easy), fabfilter, native instruments stuff is top notch! absynth is out of this world if you know how to use it (well thats pretty mcuh with anything) and if your rich.. certain waves packages are goooood!
though, i would recommend just buying a good qulaity cheapie and practice all the basics on that (with synths) and use the on board process effects on your DAW to start with to get the feel… if you got logic, youve got osme of the best processes you could use! ableton is good as well!
got Ableton 8 and the only thing I have purchased is Minimosta as it was cheap! and a keyboard to mess around with, so far having lots of fun just pissing around, plus a few tips from producer friends on building drum patterns.
after you’ve picked up all your synths…
i recommend PSP Vintage Warmer 2…
it sounds niiiiiiiiiiiiiice when applied to really hard digital synths… 
thats good man.. keep it up! i think ableton and reason really helop beginners understnad routing and the basics of production!
haha i hardly have any synth plug ins.. most of my plug ins are all processes haha
