Tom, I have purchased some of those products in the past.

I found that the (bell brand) mini-pump was not a good product. I spent a lot of time and nearly blew out my arm trying to inflate a kenda tire to 60lbs of pressure. I compared that to a Topeak mini pump a friend had and IMO the Topeak was worth the extra money.

I use the BELL wedge pack and it has been just fine. It looks a big and stupid but it is a much less expensive than most at the LBS.

My wife bought me the U-lock (masterlock brand). You probably won't find rave reviews about it and i'm not sure i'd trust it in a high theft area. Honestly though, where I live it is enough to deter theft.

I purchased one of the headlights about 2 years ago. The LED is brighter than the old generator lights I have on some bikes. Still, I think there are probably far better lights for just a bit more money. They are probably fine for someone farting around the Cul-de-sac late at night. I would rather buy the 5 LED Mag Light for 15 dollars and find a way to attach it.

I haven't tried the computers but I have been tempted by the wireless one. Why not give it a shot right?
