cheap shocks for lift?

the rear shocks in my 08 dclb w/3 inch rear lift are 100% fucked now so time for an upgrade. ive been saving up to redo the rear suspension properly but i need something cheap to run for the time being. are bilstein 5100's (extended) my only option? ive tried searching online but maybe im retarded as i cant seem to find anything. i dont want to blow the money ive been saving to redo the rear suspension right now if i can help it.

any ideas as to what shock options i have that are relatively cheap? (100-150ish for a set?)

 

thx. but are bilsteins my only option?

 

awesome! thanks. im driving to edmonton in a couple weeks so that would be my time to grab shocks and hopefully some 886 coils!
