Something will show up at some point, even if it's not really what you're after. I'd settle for a shitbox crunchy if I couldn't find anything else. Less than a fiver to fill the tank, and it'll last you more than a week.
Get a cheap DT or TS. Might not be all bling like a faired 50, but it'll get you from A to B just as quickly, and insurance is likely to be cheaper.
I know you said you don't want a scramber/crosser but it's cheap and it won't cost you an arm and a leg if you have a little off.
My first road bike was a Kawasaki AR50, looked weird as it had massive skinny wheels, but it was plenty quick enough for me. I wrote that off and managed to pick a RS up for pretty cheap. Yes it was better bike, but I was happy as Larry on the AR.
Edit: If you do go for an RS, go for a pre 2003. A friend of mine a couple years back got a 2004/2005 and it felt completely different to the previous ones (no, i'm not talking about the old ones with single sided swing arms). They for some reason felt more strangeled even though it was pretty much the same bike.
