Icom IC-R20 Scanner

Anybody out there got an Icom IC-R20 scanner? Looks a nice bit of kit but have no idea how it performs. I wonder if it scans memory channels faster than other Icoms, they always seem rather slow on scanning (or is it 'searching' according to Icom) If you've got one please post your opinions here. I would also be interested to here from anyone with a Realistic/Radio Shack or Uniden scanner as I have no experience of these radios at all.
