- various wires and a $3 switch.

I am still using it for early morning commutes this year.

The downside is that the battery weighs 3 pounds and is bulky, so I carry it in my rack trunk bag.
However, a lot less $$ than I see quoted above.
The bulky part...and the 3 pounds...and the fact that it's an SLA...are the deal killer for me. I'd rather not take up my luggage space with a brick. I don't carry panniers except on very rare occasions - and some of my bikes can't even take them - so I use a trunk bag almost exclusively. Putting a brick in it would mean that I have to take something out.
