I have been wanting an R-59 for a long time but I wanted to wait until I resolved my undercharging/overcharging issues first. Now that I have the electrical issues resolved I find out that NPD, Ames and I beleive C.I. no longer carry the R-59 due to it's high retail cost (over $300 plus shipping)! NPD told me they were working with another mfg. and were close to a deal to produce them and be able to retail them around a $200 price point.
This was last summer, I have not inquired recently due to budget cuts here on the home front. LOL I do have a couple of friends who have them and they have not had any issues at all with them...
