pordssam89I have one of those! I never tried for a record spin but typical spins are 3-4 minutes. It's pretty fun! There is a kickstarter campaign right now for a hand machined top with a sapphire sphere...might be worth checking into.
pordssam89$85 (not including shipping) for that top compared to $33.64 (shipping included) for this top. I'll happily take a slightly inferior top for 1/3 the price, since it's just a damn top.
