Sirius Satellite Radio Inc. (SIRI) Chief Executive Mel Karmazin said Monday that he would like to buy arch-rival XM Satellite Radio Holdings Inc. (XMSR), but price and regulatory hurdles would be an issue.

Karmazin, speaking at a conference in New York, however stressed that Sirius' business plan "doesn't really involve our doing a deal" and indicated he wasn't interested in Sirius being bought.

"Regarding XM - would we like to buy them? Sure. We'd love to buy them. Price would matter, so that would be an issue ... (and) there would definitely be the regulatory issue," he said.

"From our point of view, we don't see — other than if it was in the best interests of our shareholders — that we would be interested ever in being acquired," Karmazin added.
