Welcome to EpoS Wizard!
what you are asking for is going to run way into 4 figures - and i'm not talking 99.99 either!
I quite like quarion in this role due to the availability of an over all screen/consol protector
just what you need in a fish n chip shop environment being rom based, the price includes both the hardware and the software - take care when getting quotes that that is the case.]
good luck with whatever you choose 
Yes it will run into four figures. Depends on what hardware you go for. In that respect you get what you pay for. Normally Integer uses J2's but some customers run it on their own (not always the best) hardware.
Just for curiositys sake what do you envisage paying?
The company i work for would not be able to provide you with so a system.
Yes and be careful dealing with software companies that appear cheap - or even free, but then will claw back the money with a monthly or annual renual!
with both the Quarion and ICRTouch you buy it once and own it! As is the case with all rom based till solutions
