I am assuming its kinda like the Best Buy scheme. They put a different model number on it ... like they do with furniture and bedding.
Being a CEDIA certified custom installer and retailer ... I can say that anything Pioneer makes to do with Plasma rocks.
I also will say with experience when huge retail chains use their muscle ...sometimes they force manufacturers to cheapen certain items to offer them cheaper. Walmart is famous for this.
So they might use a lower grade board ... or cheaper wire ..ect to cut costs as their buyer has demanded.
If you cant compare it to a large customer base ... i would stay away from it. In the end ..things like this only hurt the people like me that support the "real full throttled" products.
Just saw a pioneer 50 inch Plasma at Costco, model PDP50A5HD. Cant find info on this model. Is it similar to the pioneer pdp-5060HD? Any feedback would be helpfull. Thanks
