so i was lurking around craigslist and suddenly i found this roller
it cost $50 and i think if i buy the new one it will cost about 160-170 if it is the same one as the roller below*
however i want to make sure if i should really buy this or not, because i don't really know much about roller, does the drum still look good? how should i know if the roller is still good? what should i check?
