What are Araya TM-18 rims like?

[Kole Kantner]

I am thinking of getting a set of LX 7-speed hubs laced to Araya
TM-18 rims by mail order. I would appreciate any info on these rims,
particularly rim width and quality (your experience). Mostly I just
want to make sure these are decent ATB rims that don't have some history
of problems. I did see one post awhile back about the braking surface
warping for someone, but perhaps that wasn't caused by the rims. Thank
you for your help.
