It appears as if you have been doing your homework...all three choices are very good - for .40 sized planes. Don't forget about a .40 sized 'Stick' (or Stik as they were originally named).

If you want to go with a .60 sized plane consider a Bruce Tharpe Venture 60 - it will be probably the best building kit you will ever build!

Don't worry about biting off more than you can chew - if you stay away from the Extra's, Giles, etc.

Keep us posted!
