Thanks for the recommendation JP.
I've never actually tried the Myer's as I've basically been warned off.
Havana Club Anejo Especial is available for 500NT at RT Mart, and I think it's a really nice go-to cuban rum. I had it as a basic rum and tonic with a little lime the other day and it was bloody delicious.
The others I've seen, I haven't tried, but you might want to:
Havana Club 7 Year is a bit more expensive (maybe 1300), and available at Breeze.
The Angostura Rums can be seen here and there. There may be the whole range at one place I found, but I'll have to see if I can find the namecard. They sometimes get good reviews. I've seen the odd bottle here and there at other liquor stores, too.
Ron Zacapa 23 Year is a premium rum you can sometimes see at City Super or Breeze. Some people rave about it.
I might have seen Appleton at one place, but have to check.
The Jingmei liquor store I mentioned in this post
has the Ron Zacapa and the Angostura 1919 (as of a couple of weeks ago).
I'll see if I can dig out some more details later.
