Trade

Rollers generally sell for between $100 and $200 around me. Much more and you get get a blaster with the engine blown up $300 to $500 around here.

Personally, I'd try to sell the stereo equipment and then purchase the roller outright.
 
i'd do the trade. f**ck a ghetto blaster.



by ghetto blaster i mean stereo. not the quad lol
