Siemon and Leviton both produce Cat5e rated 66 blocks. The pin spacing differs from the Cat5 rated blocks, but otherwise they are identical. Not sure I see a real need, though.
As to the topic, I'll use a short length of CMR/CMX Cat5E to bring in multiple lines from the NID, in the case of a small business or residence that has 2-8 POTS lines. Immediately dump to a 66 once inside. The PVC jacket on "regular" Cat5e eventually becomes brittle and falls away when exposed to the elements.
