Nice Peak Led Vance. Those guys are right down the street from my house. It's tough to find "US made" lights other than Surefire and Elzetta.
I use a Surefire C2 with a Malkoff M61 drop-in or a RA 170 by HDS. Since I can use RCR123's (rechargeable CR123's) in the RA light, it tends to get quite a bit of use. These lights are in the $150+ range.
For smaller lights, I use a Peak El Capitan which can take any AA including L-ion rechargeables which bump up the output significantly. Peak LED solutions is down the street from house and makes their product in the US, so I support them. Peak has a slew of lights. You can get them from overready.com or
http://www.em-mgt.com/LED/Peak.html.I do have two Fenix lights, an E01 and E05. I am a big fan of the E05 for about $20. The E01 is tough, but the purple tint from the 5mm LED leaves something to be desired. These are AAA lights mainly for walking around at night or letting my kids use.
I also have the Photon like lights from Countycomm that are pretty handy.
