Both are super rare in the US. I'd sell my 300 and buy one in a heartbeat if someone offered one to me here.

They should be around in some form of supply in the EU though, maybe not common but I believe they're around if you look hard enough.

edit:
for that price it's a good bike so long as it's running

edit2: watched video
I would look at the bike, buy it, clean the carbs and check/adjust the valves and check everything else before proceeding to ride the wheels off of it

I have a Canuck friend, someone gave her a beaten to death ZZR250, I told her her if she didn't want it I would gladly take it off her hands.

So far no travel plans for me ...... Yet

Buy it and make a build thread! :) Price is super cheap, you can f around with it for a while and if you don't like it you could easily sell it for what you paid.
