The biggest problem with Botach is that their online catalog has very little relation to what's in stock in their warehouse. If you call them on the phone (either for your initial order or after wondering why your stuff hasn't shown up yet) you will usually be able to avoid/resolve any problems.
I ordered from them once, and it took a few phone calls before they finally shipped my order. I imagine trying to return or exchange an item could be a nightmare, so I haven't gone back.
FWIW, I bought my Surefire Z2 from
Arizona Gun Runners, and I see their current price is $64.08. I did have to exchange part of my order with them, and the process was very smooth.
Also FWIW, if I was to buy another Surefire, I'd get the standard 6P, since not many holders fit the Z2, particularly the combo magazine/flashlight holders.
