Granted alot depends on use, maintenance, LUCK, etc. I maintain EVERYTHING I own like crazy. I am very anal about maintenance. I'm looking at the the LAZER Z HP 56" with 23 Kaw aand Lazer Z 60/27 Kohler, among other manufacturers. I am BRAND NEW in this, actually haven't even started yet. Just shopping. Don't know how many accounts I'll end up with, so don't know how many hours I'll be putting on it per week/month/year. Is there a "benchmark" like 1000 hours, 1500, etc that people heve been obtaining?
