depends on the power of the motors. Direct would be best probably but may need the reduction to get the necessary torque.

Mine are attached direct (flex coupling) to the motor shafts.

I think that only you can decide that. If you could obtain a torque gauge to measure your required axis drive torque, then say multiply it by 2. If this figure is less than your available 277oz you should be OK without a reduction.

Perhaps others may have a better guideline than this.

Hello

Best performance in an inexpensive drive is the Gecko G540. $299, but it's a 4 axis drive. If you want the best  bang for the least amount of money, and you don't mind soldering, look at the HobbyCNC. It's unipolar, though.

There are a ton of chinese drives on Ebay for under $100. Documentation is supposedly very poor, and I haven't heard of any user's experience with them.
