Hi there
After reading this guide, I must say, info is certainly helpful. However, it is certainly recommendable to get the basic first time right.
Try to get book like "Penang Discus" which cost you less than $100 that can certainly save you hundreds or thousands of dollars, most importantly, your efforts and time are not wasted.
I do have to clarify, I do not have any vested interest in this book other than looking at the welfare of a hobbyist, cos it is a common mistake make by a hobbyist, resulting into wasting money, effort and most importantly time.
Hope this helps.
