If you are looking for used gear, you can go to newenough.com . They sell used leathers and left over stuff. You could also try E-bay or any of the sportbike forums (like sportbikes.net). I belong to TLZone and guys are selling used gear all the time.
As many of the others have said, a starter bike can be anything. As long as you can handle it, be smart and take your time. I has a Yamaha Special when I was in high school and then had nothing for 6 years. When I got back into biking I bought a 1990 CBR1000. It was big, heavy and all top end, but it was fine for me. I graduated to a '98 VFR800. I think this was probably as close as you can get to a perfect bike. It is very comfortable, great sound, and can handle with most of the sportbikes. I then had to have an R1 (see my sig). That kind of bike is a beast and not for a rookie. That bike was too much fun. I also had a CBR600F3 track bike. Great bike that crashed well and had enough power to have fun, but not too much to get you in trouble (well except for that high side I did in front of the wife at Summit Point). I now have a '97 TL1000S. It is a lot of fun, has great looks and that great big twin sound. I still get thumbs up for it even though it is an eleven year old bike.
Do what ever is going to work for you. I think the SV will keep you happy for some time, but I can not say for sure. I never rode one. I think the 919 wouldn't be too bad for a starter bike if you are smart and don't pressured into stupid too easy.The VFR would be a nice bike, too. It's all up to the rider.
