It took some time really. I'd find an acceptable one and train it accordingly. If I came across something better, I tamed it, bonded it, then trained. Only then did I give it away (the 1st 2 or 3 at least to friends) or sell/trade (the last 2). All in a span of about 6 months. Now, I have the one I want and my friends have pretty decent ones too. I still run through Destard and Valor occasionally and lore the spawn just to see what's out there, but I doubt I'll find something better that suits my PvM style of play. If I do, a friend gets an upgrade or I get a little more gold to spend on stat scrolls. It's all about timing (ok, luck) and patience.
