I've been in this stock since 1994 and (obviously) don't mind being patient. I don't know when/if they will get to $3 - I'm just saying that is about where I would consider selling at this point since I've already made my money back and then some, so I can now just take a free ride. Around $3 is where I would make a million dollar gain on the position. Otherwise, I'll either probably ride this into the ground or leave it to my kids.
Their customers are government agencies that can't just reach into their pockets and buy a system. They need to go back, put the buy in the budget for future years, and then fight to get it funded while other things do not since budgets tend to be fairly fixed from year to year. I wouldn't be surprised if these trade shows generate business two or three years out.
