I dont know if PRSAs have the same rules applied as has my personal pension, but if they do, I would not put my SSIA money into one - no way!
If you have money in a pension you will only be able to get 25% of the sum as cash on maturity. The rest, by law, has to go into an annuity. In my case €20,000 buys me a useless €1100 per year. About enough for bus fares!! Anything less than approximately €200,000 in an annuity is not really worth considering.
My capital is tied up in a useless fund. Even if I was dying and needed to pay for a life saving operation, I could not get my hands on the cash. Then if I died, my wife would get nothing.
I would say in my experience stay clear of pensions. Put the money in a saving scheme or investment, at least you can get your hands on it if you need it!
