At the 1st release, just like the Garmin Colorado is undergoing now, they had a few issues but they are pretty good about listening to the public and have made great strides to correct the issues that they had. The PN-20 can be bought on Ebay for around $250.00. Tiger GPS has the bundle for $350 with the $50.00 rebate. That includes the Topo maps and 1GB card and card reader,not a bad deal.
