I'm afraid you'll have to content yourself with Joinmarket at the moment. It's been around for a long time and is fairly battle-tested but the learning curve is pretty steep and you have to be very cautious. You could be surprised by the fees. I remember back then when I paid dearly over and over again even though I had read the documents very carefully, watched several tutorials and tweaked the config file, but considering the current fee market things can't go that wrong :)
