if youre looking for something to view your trichs. Radio Shack sells good scopes for $20. Jeweler\'s loupe, go ask a jeweler
i found a super cheap jewelers loupe at one of those science stores in the mall but the most i could get is 10x. the scope radioshack has is effective but i dont like having to adjust it while i\'m looking at live buds. i think everyones best bet would be a 40x loupe if they exist
