Well, while it's possible to get very good beer for a reasonable price, it's really pretty hard to find good high-alcohol beer for cheap.
Cheaper high abv beers tend to taste like a macro mixed with corn syrup and a shot of wood grain alcohol, so be forewarned. Also, it's hard to put away large quantities of good, strong beer, as their complexity makes pounding difficult.
I'd suggest just an IPA of some sort, at 6.5% or so you'll get plenty of
"bang" and it'll still be drinkable. Still, if you want ludicrously strong stuff, here's a link to Ratebeer:
