Recommendations on a Point of Sale system that integrates with Quickbooks for Mac?

I run a mid-size retail store that uses Quickbooks for Mac 2010. Does anyone out there use a Point of Sale software (third party-Quickbooks doesn’t make POS for Mac) that they import into their Quickbooks for mac? I have read about Lightspeed and Checkout but can’t find many helpful online reviews. Thought I’d ask the collective! Thanks
