They aren't £13 new, at least not after the price hike. surely! They are aprox 20-25, sometime more.
The cheaper one is the UN51 I believe. Also, the UN54 DOES have a metal lHS locking collar. As it happens though I do prefer the plastic locking collar. They are lush.
That said, I can help.
I have a 107mm 68 emglish threaded UN54. Its been well used, and the outer shell of the BB is a bit mucky and rusty or what have you. But the bearings are in as new condition and the spindles are AOK. Thus in terms of performance its excellent.
