I agree with everyone else, they are a very nice lens, particularly for full frame cameras - the field of view for APS-C is a bit "unusual" at 35mm equiv. of 52.5-105mm. $48 is a very good price compared with what they go for on eBay UK which can be £70 and I've seen them go for more! The only snag is the "macro" setting is only at the wide end and they don't auto-focus in the macro mode - but there is an easy hack.
