Since you have shot the Taurus for years, you're used to a fairly heavy trigger on a DA 22. I would suggest you try to find one of the new Ruger SP-101's. You'll probably be happy.
The trigger pull won't be any better. I handled a new SP101 in 22lr at the LGS recently, and the trigger pull was very heavy. It seems most 22lr revolvers need a heavy trigger pull to consistently ignite a rimfire cartridge. That said, the Ruger should last a lifetime, and be very reliable.
