I got my SAI std sort of in a rush before they got banned in Md and paid a bunch for it at Cabela's. Then after getting on this forum I would hear of prices well under $1,500 for a std. I think if you can get those prices where you are at then get an SAI and you'll have a lifetime warranty if you get one that has an issue if money is the main issue. I know it's tough to check every thing in a shop or if your order one in before you shoot it. Some places don't want you field tripping it all up and down when they are showing guns, etc.
Edit:
Sorry I didn't focus on the 'used' consideration. I was thinking of new SAIs. I still could of sworn there were new ones under 15.
