What to do when most e-banking interfaces suck?

In a previous post (here) I spoke about having trouble with e-banking software of my bank.

There is a pretty simple solution - the online payment operator - epay.bg. It also can do bank transfers, so it's perfect for the task.

Epay can work with almost all bank cards, it's cheap, it's user-friendly, it's reliable. It's the perfect solution.
One minor drawback - it can't check balance, because for sometime now most banks don't support that feature for epay :(

Still I'm going to use it. I can check my balance using the e-banking app.
