Is this controller (10amp) 4 axis any good?

[ljogwin]

I saw this controller on e**y for $150 and it says" MC433 4 Axis Stepper Motor Controller 10A PWM"
Description :
Overview

The MC433 is a multi-microprocessor controlled 4 Axis 10A Unipolar PWM Stepper Controller that attaches directly to a PC parallel port. Each channel supports variable PWM control and can be individually set for Wave step, Full step or Half step. Using four ATmega168 8bit RISC microcomputers the MC433 provides user adjustable initial on time, duty cycle and duty cycle slew rate using three potentiometers to match the drive characteristics of almost all stepper motors. Direction and step commands are fed to each channel through the PC compatible parallel port interface. The MC433 is designed for high performance unipolar stepping applications. The MC433 is ideal to drive a CNC Sherline, TAIG or similar Mill with room to spare for larger CNC projects.



MC433 Hardware
The MC433 uses four AVR ATmega168/88 8 bit RISC microcontrollers to individually control the PWM output to each of the four motor ports. Using high speed Power MOSFETs each channel can sustain 10A and peak at 33A ensuring support for the most demanding stepper application. Stepper input voltage may range from 7V to 35VDC. Limit switch detection logic on each channel is routed to the parallel port connector for host software control of stepper halt. Four output control lines are available to control external relays or related devices via transistor boosted pull down logic. Power for board logic is jumper selectable from stepper motor supply or a seperate wall mount DC adapter.

Has anyone used this item? Is it a true 10Amp stepper controller?
Any help deciphering the specs on this controller would be appreciated.

Reading the specs on their site:

Looks to be a lot of controller for the money if you don't want/need microstepping.

(I've only read their website, havn't used one....)
