I have used AA1 and AA5B for business travel in North for thousands of hours. The Tiger (AA5B but NOT AG5B) fits your bill and does a fantastic job as a 2+2. There is an extremely good aftermarket and community in support, and you have one good shop nearby and a second not far away. Just for comparison: I have left one slot behind a 200HP Arrow on a two hour flight and landed destination well ahead. They are a LOT faster than P/C spam cans, and (from running light a/c maint business) much cheaper to maintain. Also with your budget can be modified to go even faster.
AuCountry Aviation, Grumman Tigers and Cheetahs for reference.
I am not very familiar with the Da20 and 40, but they, too fit your budget and speed range. only the 20 with Continental will meet your speed and fuel consumption requirements, and can not see why you would not want to fly it IFR (especailly later model glass panel). An AA1 with 0-320 mod will come very close as well for a lot less $$$$.
