Edited Date/Time:
after thinking about what cranks would be the best for my budget, these are the "final" options.
i can get the wtp cranks for 104 pounds, the united for 99 pounds and the DK social for 108 pounds, both spindles are 19mm so i would not need to buy a new bb, i can get the powerbites for 104-113 pounds, but the spindle is 22mm, so i would have to buy a new bb, which is not really what i want to do. so, is the extra money for the bb really worth it? is the 22m spindle better than the 19mm? i'm riding the salt rookie cranks (stock), that have a 19mm spindle and i haven't had problems with it (the left arm snapped, and the cranks squeak a lot now in autumn). i have spent a lot on my bike recently so i'd like to spend as less as i can but cranks are important so i might want to go for something better. dont tell me to buy eclat tibias or thunderbolts, these are too expensive, also, please, dont tell me to buy anything from the USA as the shipment plus taxes would make it a lot more expensive.
this is how the DK social looks, if you don't know: https://bmx-media-bucket-photo.s3.amazonaws.com/photos/products/1889/photos/2101/s600_101824240_1271190082.jpg?1293312487
