Between Health Savings Administrators and HSA Bank, which HSA custodian is your favorite/preferred, and why? I am planning on continually transferring contributions from my employer's high-fee custodian (HealthEquity) to one of these, but I want to know which of the two is better/lowest cost. Also, how often should I transfer from HealthEquity to the lower-fee HSA? My employer contributes $500 twice a year (once in Jan, once in July) and I will be making contributions bi-weekly from payroll deduction.
