I'm a big Bowtech fan, VERY hard to beat Bowtech bows for value, speed, and power. But, I'd say they aren't 'beginners bows'.
Then again, I am DYING to get my hands on a new Mathews Monster Chill (basically a Creed with dual cams).
Here's the trick with buying bows: Pick a price you can afford, and shoot every bow from every maker that fits your price. You WILL feel the difference between bows, so let the live fire testing determine which you buy. No online reviews, user recommendations, spec sheets, etc etc will be able to tell you which bow will feel best in your hand, and resultantly shoot the best for you.
Side note: I'd love to hear specifically why you say you won't buy another Diamond?
