Linux Based Point of Sale?

[Brian Chabot]

Would anyone here have any recommendations on a Linux based Point of
Sale system for a small retail store?

I've seen plenty of decent small business accounting software, but not
much in terms of usable POS...

so far I'm looking at:

Quasar: http://www.linuxcanada.com/index.shtml
(Not free.)

L’âne: http://l-ane.net/
(Old.  May not be maintained much.)

SQL-Ledger: http://www.sql-ledger.org
(OK, but the interface for POS could be much better)

Tux Shop: http://www.shcircuit.com/~ross/
(not free)

Lemon POS: http://lemonpos.sourceforge.net/
(Beta...)

Anyone have any experience in these or others?  Anything I should steer
away from?

Ideally, the POS I end up using would include support for a barcode
scanner, receipt printer, cash drawer, and post display, but I'll settle
for the first two.  Also ideally, there would be a decent report
function, customer tracking, and basic inventory control.  Integrated
credit card processing would be the icing on the cake.

Anyone have any thoughts or suggestions?

Thanks,

Brian
