I am on VHI one plan 500 which is high excess €500 with little day to day cover. It includes all private hospitals including Beacon hospital for most things, some limits apply, but complete excludes Mater private and Blackrock clinic as they are considered high-tech. I think there is a Laya plan that costs slightly more that includes those hospitals too.
My plan is something around €770 per year which is a good saving on the pmi4316 which I looked at, and seems to be one of the best value besides ones that exclude a big percentage of private hospitals.
