I am slightly allergic to spending a fortune on pedals because
a) they are often the first things to get damaged in a prang and
b) the differences in expensive pedals vs cheaper ones are often not of interest to me.
For example on the latter point, pedals are made slimmer. I don't think this makes much difference to, er, anything much. Often pedals have what are described as 'sealed bearings' or 'cartridge bearings' or 'sealed cartridge bearings'. IME none of these descriptions exclude the possibility that the pedals contain nasty nasty bushings...
So (for my money anyway) I like DMR V8s, because they have serviceable bearings, which (after a while) run pretty smoothly, they last well and don't cost a fortune. (It seems that other DMR models have bushings in them, so I'm less tempted by those....). However if you don't want to shed tears when you wreck them, and are prepared to live with less aggressive pins, less good sealing and no grease port, you can get by with a set of wellgo LU-987, (which are that rare thing, being both good and cheap). AFAICT the axle and bearings are similar to DMR V8 (which are made for DMR by wellgo I think). Provided the water doesn't get in (which means a bit of greasing from time to time) and they are adjusted well, they can last for donkey's years.
LU-987 are not expensive, eg £7 at cyclebasket, presently.
