Some recommend holding off a little longer, say until master level, before investing in new equipment. As mentioned, you can sell back, but at 25% of what you paid.
In the meantime, if you are looking for a little more distance to help you through the pro/tour pro tees you might consider the wgt pro 9.5 driver which is a decent value at a modest 250 credits, and will teach you more control as you get ready for master gear.
If you are itching to buy something now to make a real difference to your game I would invest in a good set of 2 or 3 wedges (many drop the the hybrid club to get 3 well-spaced wedges in their bag: you can punch a shot quite effectively out of the rough with a fairway wood). I still use the level 26-31 Clevelands at legend level, and am still happy with them.
Others here may also recommend a higher end putter (that will also likely stick with you for a long time) to slow down the meter and help your game on the greens. -Keith
