What do you lap your shaptons on?

Weigh in! I am considering buying shaptons and I don't have enough yet for a full set. I could get the DGLP and a 16K or I could get a set (1k, 4k, 8k, 16k) and a D8C to lap them on until I could get the DGLP. Here is my question: What do you lap your shaptons on and how do they work if it isn't a D8C? Any advice?


Thanks!
