updates noticeable?

would a noob be able to tell the upgrade differences between same bikes of different years?? Would those updates make that big of a difference for normal street riding? I was looking at a k7 or k8 750, but my money is kinda funny and my credit wont get it, so now i'm looking around the k3-k5 years. http://www.cycletrader.com/find/listing/2003-Suzuki-GSXR750-93082070 or http://oklahomacity.craigslist.org/mcy/749701047.html either a good deal??

If you're a noob to the sport, don't get the new bike anyway, because you'll drop it a few times and go thru noob-screw-ups, and you don't want that on a spankin' new bike. Any differences will be negligible if even noticeable at all between all those bikes you mentioned to a new rider. In fact, look for a 600, it's more forgiving, and if you think you need and when you think you can handle a little more juice, change your gearing- you won't 'outgrow' the bike.

Thanks for the response. Now as far as buying a used bike, what things should I look for? Is there a milage to year ratio I should be aware of? Any physical signs besides obvious cracks or breaks in the bike?? etc etc

The average mileage for a bike per year is something ridiculously low like 1,200 miles per year. I average more like 15,000 miles per year on my bikes and they have all been running perfectly the day I traded them in or they got stolen. The more important factor is maintenance. I maintain my bikes and keep them mechanically sound, even if they occassionally get a little dirty from riding in the rain. One fairly simple thing to check is the condition of the chain. If it is way too loose or caked in crap, then the person probably hasn't been taking good care of the bike. I saw a bike in the shop a few weeks ago, it was a 2004 R6, and it looked like the chain ahdn't been cleaned, lubed, or adjusted since 2004. I touched it just to see, and it was freaking nasty...
