I mainly detail as a hobby but I'm starting to do more jobs for friends, family, neighbours etc and I'm looking to upgrade to a more effective machine. I just find the PC kind of taxing to use. While it was great to learn with, it's loud, not particularly smooth, and just isn't very ergonomic in my opinion. Correction speed is important to me but keep in mind I don't do this for a living so outright speed is not paramount. I just want something smooth, quiet, and comfortable if I'm going to be doing this more often. I would also like whatever I choose to be compatible with the 5.5" LC pads I already have. I'm looking at the lhr 15 and duetto right now. Thoughts? Suggestions?
