This dirt cheap fluid head for light weight cameras has been sold out for months after this video review and old article (here). It's actually still sold out on Amazon. Don't bother looking for this on eBay as they've marked these up past $60 dollars.
It's a great little fluid head for your small sliders, table skater dollies, or little DIY Jib / Crane projects. Thanks to @Chapmuzic over on Twitter for letting me know they are finally back in stock. Normally ran about $26 dollars but it seems with popularity they've added a $3 dollar mark up via B&H (click here).
