i think i last had a proper mix on my setup almost 2 years ago when one of my ancient numarks finally kicked it and won't spin smoothly anymore. i didn't have the money to replace it back then but I'm earning now so looking to replace it. if money wasn't a problem, which hopefully it won't be some day lol, i'd have four 1210s and the serato 4 channel mixer, so that's what I'm working towards. at the moment i just want to replace one deck and buy an sl1 box. so in short I'm looking for any info on what to look out for on buying second hand 1210s, what's a good price, etc.
