Electromeridian Imaging Products/Software

Hi all.
I am a licensed acupuncturist and am wondering if anyone here can share personal experiences or knowledge concerning electromeridian imaging products such as Meridia Acugraphics, EMI 5.0, or EMAS? I would enjoy hearing other's comparisons before I purchase.
I found a couple of informative posts on "Dr. Tan's Forum", but doing a Dogpile & Google search for (electromeridian imaging-forums-reviews-ratings) didn't bring up anything.
The EMI 5.0 runs around $1000. The other two are about $1800 each.

Thanks for any reply!

Best...MikeE, LAc., MSOM
