Should I transfer Amex points

1st post - please be gentle with me!
I've been saving my Amex points for an agen now and am wondering if I should transfer to Virgin. I've got around 150,000 and I understand there is a 15% bonus if I transfer before end of September.
Now, the daft qustion; will this number of points get us a cpl of flights (in UC) to New York for example and is there a massive amount of taxes to pay?
