I would like your opinion on choosing a device to analyze mutations in a certain number of genes (20 to 30), I believe the sequencing of some 500 amplicons, of metastatic tumors (approximately 230 samples for validation) and then about 20 monthly samples in the routine. We're looking at Illumina's miniSeq and miSeq options and Thermo Fisher's Ion Chef System/Ion Gene Studio S5 Systems.
What would you advise?
