just wondering what everyone is (or is not) using for the pana dvx100

i've seen

which is the same as
http://www.bhphotovideo.com/bnh/controller/home?A=ShowProduct&kw=IMSSCGL1&Q=&O=&sku=229480

same model - different construction...what's the deal?

also...I've heard good things about
http://www.dvtec.tv/

which is the same as abel's
http://www.mediumblend.com/abelstore/customer/product.php?productid=428&cat=9&page=1

studio1.com's mount is the same as the one on the b and h and filmtools site

so basically i am looking at 2 mounts.....

one the dvrig pro

and two

the studio1/filmtools/bandh mount image 2000 ( three diff models listed on filmtools site)...i like the one with one hand grip

anyone use any of these....feedback? suggestions?
