rear leaf springs for a 92

Can anyone point me in the direction to find a set of rear leaf springs that won`t destroy my wallet? I got a quote of over $500.00 for a new set. I use my 92 rodeo only in the winter to tow the snowmobile trailer and don`t want to spend that much for a vehicle that i feel is worth only $1200.00. I`d even install a good set of used ones if i could find a set reasonable.
