Looking for Spare ABS Parts to Sand

Hello I'm looking to see if somebody has spare ABS parts laying around they wouldn't mind parting with? I want to practice post printing resurfacing to see what types of finishes I can achieve before deciding on a 3D printer. I could cover the shipping costs of course. Parts with flat sides are ideal of course as sanding would be involved in at least some. A variety of micron layers would be a nice test as well. I live in Southern California so closer candidates are appreciated to save on shipping :D Anybody have old parts laying around?

Thanks
