i just noticed that costco has the mx-500 for $99.99
[Link: costco.com]i usually try to buy high priced items at costco because of their easy return policy; EXCEPT when i bought my mx-500. i went with blue-do because if, god forbid, anything should happen to my remote, blue-do can clone it for me to save me the programming time.
(and to save me from hearing my wife say "would you just STOP with that thing !) by the way, local costco stores DO NOT carry the remotes, they are only available online. since you're online already, you might as well go with one of the advertisers on this forum.
