Sorry for the post, you did say Used or New in the original.
New SL Lift is going to be around the $1700 mark and it may not include Shipping.
So you want either a USED Lift or a Cheap New Lift, SL or RCD.
IF it was me and I didn’t have the SL I would buy the RCD one, comes with Coil-Over Shocks, nice.
ltr, good luck...
