What's a Good Replacement Rear Diff for the E-Maxx?

[rawfuls]

So I should be looking for TMaxx 4908, or EMaxx 3905 diffs, right?

Those are some neat diffs Gee, but, damn, that's a lot of money I can't deal with... right now.
But hmm, I will be getting about some cash flow in pretty soon, how much would you bid for that?

Like, the max, you would lay down for those two diffs:
