I offer them on ebay for $44 + Shipping. It is not hard to just build your own. 3ghz core 2 duo machines with 4GB and room for a 2nd NIC are the way to go to keep cost down in my opinion.
I only entered the market by accident. There is not much of a barrier to entry. I bought 50 machines from a recycling company in Maryland for another project. My friend suggested putting pfsense on them and selling them on ebay to help get rid of them. Your lowest cost product is $299. I am sure you know this industry better than I do. Ping me offline if needed.
No, we only sell ~4 machines per week. Profit margin at this price is thin. Maybe we need a better marketing campaign :) The machines without hard drives cost me $20 each. I got a bulk deal on hard drives and network cards. Once we sell all 50 machines, we don't plan on selling any more.
So, why isn't selling cheap pfsense devices on eBay part of the solution to avoiding vendor spying? Because you also sell pfSense hardware and it's more expensive?
