As others have said, you're gonna have a PICKLE of a time finding an SV for less than 2000 that is in working condition - but that doesn't mean they might not have one at a salvage yard thats been resotred (remember, just because a bike has a salvage title doesnt mean its not a great used bike - just that the cost for repairs from an insurance company is more than purchase price - and considering a new MUFFLER on my SV is 1000 dollars - which is 500 dollars more than a SICK Yosh pipe, thats not suprising).
A ninja250 should be an easy find, and would be fine for your size as well, maybe even better since youll have greater control over it.
You and I are the same size (maybe 10 more lbs on me. . .uhm - im workin on it) and I love the 650, but if thats not an option, definitely hop on the 250, as it sat fabulously for me.
In this digital age, you should have ZERO problem finding helmet, gloves, boots and jacket for less than what some people spend on a SHOEI helmet. Ok maybe not that great of a deep discount but for example:
HJC-15 Pegasus helmet - 80bucks on ebay.
Joe Rocket Reactor gloves - 30bucks on ebay.
Frank Thomas boots - 60bucks on ebay.
The jacket is going to be the prickly thing. I was able to find an Icon Pursuit jacket in red for 216 on newenough.com. If its leather, the discount is going to be less than if it were textile (which is still good protection, but a bit too bulky for my STYLE tastes - it handled wind buffeting like a champion though).
But yea, if you're not able to save money getting geared out, Id say look around more. The deals are out there, just waiting to be found. I recently purchased an Icon Domain Decay red helmet for 245 - retails 390.
