Retro, don't get me wrong; I would love to own a tensionmeter. I'm just not willing to pay for it
A tensioned spoke has a nice ring to it. You true your wheel, then check for tension by plucking or tapping the spokes with a screw driver. If you find a spoke that is way off compared to it's immediate peers, you adjust them so they are as close to one another as you can get them while keeping the wheel true.
Lately I have grown lazy. I have two wheelsets, a 32 hole, 2mm DT Swiss spokes on Mavic Open Pro rims, and 36 2mm DT Swiss spokes on a Velocity Dyad rim for loaded touring. Having enough spokes on a strong rim minimizes the need for true'ing, so I just take the rear wheels to my LBS on the off season. $10 bucks a pop, instant gratification.
llmercll, a strong wheelset that won't need to get de-wobbled more than once a season would make you happy.
