Thinking of picking up the Glide Gear SYL-500 Looked into the SYL-3000, but might be overkill for the A6000. There is also the SYL-1000. http://www.amazon.com/Glide-Gear-Vid...pr_product_top Does anyone have any experience or knowledge they can share about either of these? Is there another brand that you would recommend? Or forget about it...the A6000 doesn't "need" this contraption! *Price & quality is a decision factor.
