I, too,switched from Bellon to Parker after a nasty experience with Bellon about 7 yrs ago. Bellon pulled a bait and switch on me after I nationalized my car and I said forget them. They would not give me any refund on a policy if it is older than 90 days.
I used Jesus Tejada with AXA the first two years I lived here ( 12 yrs ago) and found him to be rather expensive, and prefer a local agent.
Locally, I would still go with Parker and ask them to give you quotes from HDI and Qualitas for the same coverage. Have always heard good things about Qualitas service when you need them, but have nothing to go on regarding HDI service (which I currently have) !
