Not really sure of any other "reputable" & reseller-focused companies that don't use LogicBoxes, EIG is getting a good deal here!
Could also be an eye opener for one who might create a solution.
Edit: It is really interesting that DirectI corporate website claims to have been valued at 350+ million dollars yet EIG reports to be possibly buying them out at 100 - 110 million dollars.
My primary browser would have to be Chrome, I use it the most no matter how hard I try to go to another .
Though since just yesterday I've started to play with IE10, I like the fact it has less distractions for me.
Of course your fees will be reduced (down to 1.9% or something) if you are processing a large number in monthly transactions. Though PayPal fees seem on par with everyone else (It is 2CheckOut for non-us merchants that charge crazy fees) - 5.5% + 0.45c!
