Slik 800 Ball Head

[redrew]

I own an Olympus C750 with 1.7x teleconverter which combined are not very heavy. Though I would love to purchase a Markins, Arca or even Gitzo ball head, I prefer not to spend that much. The subject ball head has a quick release, tensioner knob, horizontal rotation and a cost of about $80. I can find only one review, which was positive but not very informative. Does anybody have hands-on experience with this ball head and QR, if so I would welcome your comments.
