Not that you asked but I have to say, I owned the Marshall V-LCD70XP, the V-LCD50 and the SmallHD DP6. Hands down the DP6 is just superior. I sold both Marshalls. Still use the DP6 regularly and would buy it again
I have a the original 5" Marshall, as well as a 6.5". The 6.5" is HD, & designed to be viewed outdoors, so I'll be holding onto it, but I never loved the 5", & only picked it up as backup. While overall I've been happy with the Marshalls, they produce a soft image, & there seem to be better options available today.
My next monitor will likely be TV Logic's 5.6" VFM-056WP. It's supposedly based on the same screen as the SmallHD DP6, but has many more features. I've seen both attached to an Alexa at the same time, & the TV Logic's colors looked better, & more closely matched the larger Panasonic broadcast monitors.
www.tvlogicusa.com/product/img/files/bro/vfm_056w(wp)_bro.pdfAbel Cine Tech blogged about this monitor, but missed some features, such as the ability to enlarge any section of the screen, & not just the center, with 1:1 Focus Assist.

The reason I'm holding off is two part. I generally prefer Zacuto's EVF, especially outdoors, & Mitch Gross of Abel Cine Tech stated there's some new professional monitoring device coming to market soon, but he was unsure of the timetable. I'm hoping for an EVF with HD resolution
