I have written in these forums regarding R44 vs turbines:

If money is no object, go for a turbine. If you need to perform specialised work e.g. sling, line inspection, mountain work, go for a turbine.
If it's just to transport people from A to B plus a few scenic trips in between, R44 may fit your bill without breaking your bank.
Lastly, your decision rests on how much you like flying each of those machines. Try it yourself and see.
ps. I love flying the Squirrel but if an R44 is all I can afford, I would buy that instead.
