If you have cash, go for Corsair XMS PC3200 C2. AFAIK the majority of the Intel boards have memory dividers whereas you can run a 150fsb but maintain a 200 bus memory speed and make sure of the Corsair XMS PC3200 (200fsb) at CAS2.
Crucial PC2700 is good but don't expect to get 185fsb and above with CAS2, but seeing as you're on a budget, I would recommend Crucial PC2700, I'm hoping for someone to post discounts on it. There are various things you do to get a 10 - 15% discount and if you're on a budget, every penny counts.
Also for a reasonal price is Samsung PC2700 CTL. CTL is very important because it means it's 'genuine' DTL means it's like fake stuff and preforms very bad. If you can get to go a local store and hand pick your memory, CTL will mark "TCB4" as their last letters so keep an eye out for that. I've seen them hit 200fsb pretty easily just at CAS2.5
Good Luck.
