Hi THT and all
I will give you my opinion as well, seeming as i was in your position last June
I agree with Sukh in terms of having some lessons, this way you will know if you are in for the long haul.
The reccomendation that i had from my Pro (Paul Ashwell - Top 25 Teaching Pro, Coach of the mens English Golf team and also Juniors) was to have cavity back game improver irons. The reason is for forgiveness. Yes you can start straight out with blades but cavity would be best for starters. I wil back Cavity's for you over blades any day and no matter what others say. I started in June last year and by following the Pro's advice i went from shooting 120 on my first round to now shooting 87!!
Im babbling now.......in short
Go with some cavity back game improver irons, Mizuno MX-17 i reccommend, Steer clear of RAM / Hippo or any other BRAGAIN Sets
Driver (Play with some at the range and go with something that feels nice)
Putter (Again play around with some at your local golf shop)
Keep your bag simple for now with Irons, Driver, Putter. learn to hit the straight and well then you can start adding other clubs
Hope that helps
