SKF 6001-2RS can be had for £3.88 a pair and work fine with the Formula / System X clones. They are smoother than the stock ones that come with the hubs and still are after 3 years use.
As for BB's I'm still yet to find anything wrong with a UN-54. I ran one for over 10 years on a Stumpy and it was still smooth when I passed the frame on to a friend.
