Referee Equipment

[BSL]

Gentleman,
I am a newly licensed high school official. I have done several Jr. high and Jr.league games over the last 3-5 years that do not require a license but was just recently able to make time to go more full time at it. Please bare with me, I am new at this, my question is. Do any of you know a good reliable source on the internet to purchase equipment, (I.E. shirts, pants, jackets)? I know of a couple of sources such as NFHS/NFOA catalog and Officials Supplies, but I thought I would ask those that are more experienced at this for some advice and opinions. In the past I have usually just picked up striped shirts & other items at local sports stores, but the quality is questionable.

Thank you,
