Moose,
I don't really think it's anything revolutionary,  just convient!.  Having a bunch of precut piece of heat shrink is handy.  I don't see it's worth what they are charging for their kit.

My problems is that I never >seem to know ifI completely 'sealed' them with heat, and that is only if I remember toput >the tubing on the write PRIOR to making the connection.  DOH! Also, the precut stuff >always seems to be 'just long enough' if that. 

Exactly.  I prefer to have my own collection of different sizes of heat shrink.  I buy it from a local shop.  No I can control the length.
For my outside Coax connectors, after they are soldered to the coax,  I connect the connector to the antenna or a barrel to bring the cable into the house.  I then wrap the connector with water proof tape which you can get at Home depot :1. Temflex 2155 - heres an alternative:
       a. Nashua Stretch & Seal self-fusing silicone tape - $8/10ft - Aisle 09, Bay 014
       b. Scotch/3M 2242 tape - $6/15ft -2. The above tape is NOT UV safe so I then wrap that tape with  Scotch Super 88 black electrical tape.
A lot depend on what your trying to make/fix/install.  For trying to repair a new car wiring harness is a real pain in the A$$.  I've used some of those butt splices with the low temp solder.  They seem to work well.
