[Highland Park] ISO drum set for my son

My son has just started taking drum lessons, and I'd like to get him a newbie kid appropriate set of drums.  Not very picky about what kind as I know nothing about them.  I don't want to invest too much in them because I'm not sure how interested he will be.  Please email me if you have some drums you're looking to give away or sell at a reasonable price.   Thanks.
