Look at ebay, check dealer ratings. This doesn't even begin to list the stuff I've gotten at incredible prices on ebay. I got my Bridgestone Mid irons, graphite shaft for $125, Callaway BBII 12* Driver $36, Bridgestone GC Hybrids for $25-$36, 2 ball putter for $55, Taylormade R7 Superquad $145 (a year ago), Nike Sumo2 SQ 5900 Driver (a month after they came out) $167. All this new! Wilson Di7 and Nike CCI (6 months after they came out) for less than $300 each.
Irons: Check out the Wilson Di7, Taylormade r7 draw, Bridgestone GC OS, or Adams a3OS (a bit more expensive, but they come with 3-4 hybrids and 5-6 "kinda" hybrids. I could not hit the true hybrids, but was able to sell them and buy Bridgestone GC Hybrids).
Get a bit more loft on the driver than you think you need, my Sumo is 16*. The Sumo's are around $100 now, but if you need to save some cash, the Nike Ignite 460 (not the 450's) can be had in 13* for less than $50 (used) and they are an awesome driver. If I were going to spend $100, I'd steer you toward the Callaway FT-i, mine's 13* and very forgiving. A lot of people have said the FT-i is not as long as other drivers, but I have not found that to be the case. Besides, 10 yards shorter and in the fairway gives you a better shot at par than 10 yards longer behind a tree/in a bunker/water/rough, etc.
Putters, very personal, but, the 2 ball line is a good choice it that's your thing. I've got a dfx, the other inserts (white hot) are too soft for me and I leave everything dead center short! I'm experimenting with the F7 because I love the look and I do play some fast greens on the odd occassion. The best all around mallet for me is the Ping Craz-e, #1 on my list. Hope that helps.
