The SKF BB kinda falls into that category. At $170 plus shipping it seems a little extravagant when one can purchase a perfectly adequate one for $25.
Stainless steel spindle, good seals, and roller bearings on the drive side, me thinks it may be more durable. But yeah, I used cheaper Shimano square taper cartridges until I discovered external bearings on HT2 cranks, and I'm never going back. The problem with even the SKF cartridge, is you cannot readjust over time to take out any slack and restore the preload. Slack speeds up bearing wear and stretches seals. With external bearings, you can adjust over time.
