Deal Making - is this OK?

[pokerstudAA]

Is there a good deal making calculator/software or something out there?

3 way at the end of a $50 / 240 person tourney.
Chips counts are:

Hero: 396048
Player A: 146768
Player B: 177184

Prizes:
1st - $3,240
2nd - $1,956
3rd - $1,080

Hero made a deal for $3,100 and the other two each got $1,588.

How can I deal if this deal was +EV? Was it? I thought it was.
