Always amazes me that industry traders say things like 1 month warranty. If they're a commercial enterprise I'm fairly sure they're obliged to 6 months minimum.
Can't comment on the one you've linked to but you'll always get a better price with a private sale.. but no warranty at all.
I've seen a few pointys around for similar price, such as this one on FB...

In case you can't view the link it's a 2005 Blue Pointy, 29,000 miles, Akropovic exhaust. (I have no connection with it, just saw it listed).
