Poly bushings??

Yeah, I plan on doing it myself. I put new stock replacement bushings in the lower control arms about 5 years ago. But it had been so long I forgot if I used my vice or a hammer...or what exactly I did to get the old ones out and the new ones in. So how do the poly bushings feel in the stock arms? Stiffer, smoother ride? Is it worth it, or should I just wait until I can afford to get new upper & lowers all together? I'm on a budget and have many different areas of my car that need attention to (attention=$$). My car just had it's "re-birth", after sitting for over 3 years. So you could imagine I have a lot of things to go through, check, clean, and replace.
