Skip white distributors

[conoco]

Have had read a lot of post with people running the skip white distributors and saying that they are very good and affordable. Does anyone have a link on here to get one for a 1972 gmc truck? I go to his website and it is mainly ford distributors, the ones he does have for chevy 350 are the MSD and they are not cheap at all. All the post I have read here say they are anywhere from 60-100 bucks, and it also says they are purchased on eBay. I was looking at just getting the MSD street fire hei with the matching coil and ignition box that whole set up is just over 500 dollars and from what I read on here I could spend 200 on the same stuff but different brand that will do the exact same thing as the name brand stuff, Anyway was just hoping someone had one info, or other suggestions on hei distributor and which coil and ignition box they use or work well. Thank you.
