I have to agree with Tom on this one, do not buy the junk from the big box stores. Their only concern when sourcing systems is who can supply them with the lowest price. In my nearly 30 years of field service, I still will not even touch or attempt a repair on the cheap units. It makes about as much sense as repairing a huffy bike. When you build something that cheap, what do you think you are getting?
BTW, I ride a Cannondale Prophet.

I agree with Tom also.
The thing about Sears is that they have to provide service after the sale. At least 10 years out,unless the law has changed. They have many makes in the Houston stores.
You may be lucky to get 5 years. No mater where you buy it, Most all is Plastic Crap.
But it is nice to know you CAN get parts and DIY, 10 or 20 years down the road.
Theory only works perfect in a vacuum.
