Today was a good day
 

Today....

I officially completed my Bachelor Degree and received Summa Cum Laude honors.

My boss stated that he and his father are going to buy a jet to replace the King Air (CE560, CE560XL, or Lear 31!). I am pulling for the LEAR :D.

... was a good day :) .

Of the list you made, I'd say the 560XL is my personal choice. Glass cockpit, APU, a bit slower than the lear, but bigger cabin and headspace. Plus you might be able to pickup a used Citation that is still covered under factory warrenty... you probably won't find any Lear 31s that are still covered.

Congrats on the degree!
