Aircraft info/advice

Thanks in advance.

I'm looking into building an airplane kit. All the experience here could
probably help me as opposed to a blind search. I'm looking for a kit that
would be consider IFR flyable. Would probably lean towards four seat but a
my wife won't fly is probably not mandatory. I would like something that
would at least approach 200mph. And I would also like a quick build option.
Metal/composite probably doesn't matter. Price is a moderate issue. A
Lancair IV-P fully decked out would not be out of reach but truthfully more
than I would be probably willing to spend. I would like something considered
safe and practical. I don't need a plane with fighter like
characteristics. I would like add a full range of equipment that I would
feel would make it safer both VFR and IFR. ie GPS, Autopilot ( can you do
this in kits ?) and IFR capable. Am I asking too much?

Thanks for any advice of planes I may look into. I haven't flown in
several years so I apologize if some of my questions are stupid or outdated.
I would like to build now and the begin flying again especially as I
approach the time I would like to retire.

One specific plane I have been looking at is Van's RV-10. Any comments on
this? Really have not come across any other options.


Thanks
