I use the Norelco one with the vacuum. For it's very reasonable price of $30, I must say I'm pretty satisfied. It isn't perfect though. If you are a perfectionist, you might want to get something more professional, because it's hard to get stuff "just right" with this one. I think it's nice to have one that's pretty good and then just not worry about making it perfect. I do my cheeks and neck and the very shortest setting (which is with the comb thing taken off) and then do the chin on the second setting. Depending on what I'm doing and how clean I need to look, I do this every couple of days or so. It's nice because I never need to shave and I hate shaving. The vacuum is also a nice feature, because cleaning up is for suckers. Since like I said I don't really to get it perfect, the whole process only takes me about 2-3 minutes. So to sum up, if you aren't a perfectionist get this one. If you want an exact model number I could go get it for you but I think there is only one Norelco beard/mustache trimmer with a vacuum. Hope that helps.
