What are you compacting? My experience is with the cat version. It does a decent job, but in very thin lifts. Generally we use 4-8 inches of stone, and 4-8 inches of sand under pavement around here. We were running it on a 277 for a while, and it seemed to do pretty good, i think the tracks helped out. When we put it on a smaller wheeled machine, it did horrible. We were doing a major parking lot, and we should have been using a decent sized smooth drum. In fact, we did not make the compaction numbers on our stone, so we had to get our smooth drum in.
If you were to be doing patches, or doing driveways, it would be worth it. I think it would be use full if you were taking it out to a complete job with a skid steer it would be worth it. Might even be nice to do utility trench paving. Just straddle the trench with the roller attachment and roll your new asphalt out.
