new springs or spacers involve the same work, you might need a spring compressor for the front, i didn't use one but we had a hoist, 2 people and a long pry bar and a guy with a really sore thumb afterwards... try national4wd, they can get OME stuff, it's expensive though and i really cannot see it being that much better, it may ride nicer but it's still a tracker! coils spacers are gonna run around $100, the OME springs more like $500. for the difference you can get your new rear shocks, strut extensions and an alignement! others may completely disagree. i should mention though that if you're springs are sagging now, replacing them will be a better option.
