Good on you, bigtim. I use a D2 as my main machine, but earlier this year, a T2 and then an F75 fell into my lap. I've put some time on both of these machines and they have their merits, but left to my devices I'll reach to my D2 when I head out the door.
The temptation to hop between machines is real. However, if you stick with one machine and learn it inside and out, it will become the best machine for you.
