b0ng0, your a man after my own heart! We have similar tastes. I first went for a digitech Death metal pedal. You can get them dirt cheap and have such a damn tasty crunch to em. I recently ditched mine though. Its not versatile in the slightest (no gain knob!), and my lead guitar just sounded messy when playing with friends. Its great for the price, and served me nicely to practice for a good year or so, but ive taken a shine to a much cleaner sound.
HOWEVER
I just bought a Line 6 Uber Metal, and it is SWEET. got it for £70 including P&P from guitarampkeyboard. Its really versatile and you can get all sorts of great sounds from it, and it can pretty much mimic my death metal pedal anyway. Its also got a noise gate, which is handy at high gain and such, and good for chunky powerchord grinding. Takes some fiddling to get the right sound from it, but im not overly experienced with these things and i had a great sound after 10 or so mins of playing around.
P.S. GAK's service isnt so great, the postage was poor, my pedal, along with another came loose in a sack and both had damaged packaging. I told them how pissed off i was but didnt get an apology. Just an offer for me to send it back and that they would compensate me with "goodies" for the postage back :roll: Plenty of sites do the Uber Metal at a good price though, its just a case of looking around.
Hope i helped

[EDIT] cr@p i forgot to mention. As for a wah pedal im going to get an ibanez weeping demon when i get paid. Apparently its really versatile so im just gonna go for it. Just going on online reviews here, apparently its good. Ill have to get back to you on that one!
