I have the X700, the XD7 (XD11) and two SRT's. I prefer the x700 slightly over the XD7.
If you can get over the plastic you are rewarded with a better grip due to the molded in grip and slightly more responsiveness compared to the XD7.
For me the handholdability of the X700 is better.
Here is a useful feature compare table for the electronic Minoltas albeit in german.
