Hey, I have some OEM wheels I took of a Boardman XC hardtail that might be suitable, the front anyway. I rebuilt the hub with my brother about a year and a half ago so as far as I recall they run pretty smooth - not sure how true they are though, but from memory they were fine. FWIW, I tried to set either the front or the rear up tubeless, but I was quite impatient so it didn't work (needed more tape), but I believe it may be possible!
I am tied up in a meeting this morning so I'll see if I can get you some pictures later. In terms of cost, I'd just like postage covered. If you like, I can send photos of the rear wheel as well
