Opinions on this kit

I have read so much that my head is swimming, but if I could ask for a straight forward question regarding opinions of the following kit for a G1006 conversion...

Promotion 4 Axis NEMA 23 Stepper Motor 425 oz Driver DM542A CNC Longs Motor | eBay


I know "you get what you pay for", etc. etc.....I am a very novice hobby machinist that got a steal on the mill and interested in attempting this conversion. comparisons of options that require the use of four decimal places and various greek symbols would be lost on me. Appreciate any thoughts on this.

thanks,
Steve
