I recently had 2 orders with anchorexpress.com and was very pleased with them. I had become leery of trying new internet outlets, having had difficulties getting my orders, but Anchor Express proved to be worry free.  
They had the best advertized price anywhere on a TP10 tillerpilot I was looking for, and in addition, had it to my door the next day for $15.  
A few days later, they not only beat everyone else I could find on the price of a Garmin 340C fishfinder, they mated it with the in hull transducer I needed, instead of the transom mount advertized. I can't get my local Garmin dealer to do that for me, and he couldn't come anywhere near the prices on either the tillerpilot or the fishfinder, and I have a wholesale account with them!  
As someone who makes my living repairing boats and spends my free time throwing money at them, a company like Anchor Express is a breath of fresh air.
