Well if you do have that fast of a clubhead speed, you may be SOL on cheap driver shafts. If you want something that fits you, you'll need to see a fitter with some tour quality shafts not found on the mainstream market. Even tipping a heavyweight shaft by like an inch might not be enough. Less loft is almost a certainty. You won't be able to buy anything off the rack at all.
Forget about cheap though. You might be able to find a decent consition head from a couple years older model around 100$ like an adams 9064LS, which is notoriously low spin, but the shaft could be a couple hundred unless you don't mind playing something a bit soft for you.
The Grafalloy bimatrix is supposed to be decent, 80g in X flex and 80$, but I don't think it's enough unless you go to like a 7˚ head. It's the same model Bubba Watson plays, but I doubt the market version is close to his spec. The UST Mamiya Proforce V2 in the 80g range tipped might be an option because it's so low torque, but you may need to tip it and it's 80$. The UST VTS series comes in a TX flex at 150$, and can be found in the 80g range as well as having matching shafts for the woods and hybrid. The Project X graphite wood shafts might be a bit soft, even at the 7 flex, so look at the tour issue models at high prices. Then there's the nunchuk, which supposedly works at any swing speed; it's pricy as hell but Jhonny Vegas uses it and he's one of the longest hitters on tour.
At this kind of swing speed, the margin for error is very thin. So get fitted and find something you can hit straight, for the love of god. And don't guess your SS, get on a real monitor at a competent fitter. If you do, you'll spend the money once and get the best results. If not, good luck out there buddy.
I suggest you play a driver no longer than 45".
