Experience with Superpro (trailing arm bushings)?

[scratchgolf135]

I'm installing all the M3 arms along with the ECS trailing arms and want to upgrade bushings while I'm in there. The powerflex bushings seem exorbitantly expensive for how small these particular bushings are while the Superpro seem to be more in line with what I would expect. Anyone have experience with these particular bushings or with Superpro bushings in general? I read on some other non-BMW forums and people seem to like them a lot but have any of you used them for your e82?
