Advice on VISA IPO?

I missed the boat on big IPO’s like Amazon, Yahoo, Google and the likes. VISA is geared to go public sometime next year.
MC started at 40.30 and is now 215.46. Would it be good advise to put some money into it, long term. Since I am new to this - on line trading, is it as good as having a broker.
Thanks in advance for all advice.
