ok. I will stick with something like what sparkfun sells.Much better prices on boost switching voltage regulators on E-bay from Asian sellers. I've bought several types and have never had a problem with them. Here is just one example:

Have you tested the step-up regulator with much of a load? I ask because I would like to run about 140ma of blinking LEDs of a minimal Arduino using a 3.7 lipo battery. It would be awesome if the regulator could truly supply 1A at 5V.
I don't own that specific regulator, I just posted it as an example of what is avalible from Asian sellers on E-bay and there are many many others to choose from. I have bought similar regulators (step up and step down models) and have had no problems with them. Their main advantage is their higher efficiency ratings Vs linear regulators and when powering a project from batteries that higher efficiency is a real benefit. The output current rating from that ebay listing shows:
Input voltage:1-5V
Output voltage :5.1-5 .2 V
Output current: rated 1A-1.5A, 1.5A maximum
Conversion efficiency: up to 96%
So I see no reason it can't meet it's 1 amp stated rating.
