akai s20 - i've got this one about five years ago,sold it,missed it...cheap,excellent and great/oldskool sounding for phrases/loops
alesis mmt8 - somebody ask for sequencer,my friend got this for cheap,and it's superb and easy to work,a whole bunch of techno producers used it back in the days,but novadays it's hard to find
and i can recommend electro harmonix pedals/fx - they do really great job for me,and they are relatively low priced compared to big box fx,i specially recommend holy/holier grail sping reverb and electric mistress flanger...+ i wish i had e.h. memory man delay
edit: one more find:
there is dp4+ on this image but dp4 is equally good,great and cheap (as for 4 separate fx) box,i use it all the time for kick/snare compression but it's capable of doing a lot more
