Like Brett mentioned, don't buy a Ricoma. We bought a new Avance 4 head (which is a rebranded Ricoma) 4 years ago. While it has paid for itself easily it's been a huge struggle all of the way, especially on hats. We picked up a 2015 Barudan single head last summer and have blown away by the speed and quality. So much so that we just pulled the trigger on a new Barudan 6 Head compact which should be here in a couple of weeks.
The plan is to leave the Avance for flats and dedicate the Barudan to hats, and only convert one or the other on large runs. I can't tell you how excited I am to never run a hat on the Avance again!
