Unix Based Point-of-Sale Systems?

Silent Node asks: "I am currently working for a ski and backpacking shop in Jasper, Alberta Canada (Everest Outdoor Stores). Right now all the inventory, sales system, rentals, etc. is being done the 'old fashioned' way (read: paper ledgers, circa 1980 cash register w/cryptically translated manual and 50 bytes of memory). This store is planning to computerize their POS (point-of-sale) system in the near future. I would like to advocate a Linux based solution, but don't really know what's out there." Quite a few people have been submitting questions about Linux-based point-of-sale systems, and we did touch on those waaay back in April, however now it's 2001 and to my knowledge at least one more vendor of Unix based POS systems has popped up on the radar. Are there any more options? And how have the systems mentioned in the previous article kept up with the times?"

"This is a small business (under $1,000,000 a year in inventory). This system needs customizable for both our rental and sales needs. Cost is a factor. What POS systems, and support packages are available that would fulfill our needs?"

And in a fortuitous happenstance 10 hours before press-time, swagr, who is assisting in the search for a Linux Point-of-Sale for a women's clothing store, slides in this bit of information: "I figured a Linux-based solution would be the lowest cost...so I did a search for Linux POS software and found only this. Doesn't seem like there's much to choose from. Anyone used this or heard of any open-source equivalents? Check out the (lack of) activity on the open source POS mailing list . What's your take on Linux in the retail sector?"
