Tried of the 57mm Winter altimeter being too inaccurate even after being re-calibrated. Being EXPERIMENTAL, going to look into digital.

Going to look at MGL Vega ASV-1 first as it displays altitude and airspeed. http://www.mglavionics.com/html/vega_color_singles.html

Anyone had experience with this specific make/model?

Even though you are experimental, your airworthiness certificate may be linked to a particular set of basic instruments. Best to check it out before you remove the Winter.
I have used an MGL engine monitoring instrument and thought their quality and documentation was above average. The new instruments have much improved readability.
