I now have both the Dwyer Model 25 MKII and the Magenhelic 2000-00, and I may be the first to say this, but I actually prefer the Dwyer Model 25 MKII. If the Magenhelic is not mounted perfectly vertical it will not read the correct value for draft. It is not anywhere near as forgiving. It is also smaller and in my opinion not as easy to read at a distance. I may end up with both installed side by side for awhile to give the magnehelic more of a fair shake.
