As mentioned the gas gas 200 is also worth a look, may come up in the same condition but at a cheaper price (they are cheaper to start with), it's all a bit hazy now, but i rode one a few years back that had some power valve or exhaust modification (american i think?), and this gave the bike masses amount of bottom end torque...almost on par with my Te 410 husqvarna that i had at the time.
Good choice anyhow!!
