Knowing some of the clubs you play at (we live close by) then I think it is a great idea, the lack of any sand at some is pitiful ! Go for it, get the shiniest you can !
Recently bought UA from Complete Golfer (have website) and they are perfect. I am xxl in most things and shorts can be a challenge, not this time. Good luck
I recently bought these for my RSI 1 irons which are not small, they have worked perfectly so far

Golfbidder is good but a bit expensive. PGA Pro's sell alot on ebay and often it is brand new but one model older, bargains and deals to be had. Good luck with your new Golf career
