Reliable Front Suspension Fork

[MiraVelo]

Which front suspension fork would you advise me to purchase if I switch from a rigid front steel fork to tour the Great Divide route? Previously I was just considering using my steel rigid front fork on my hardtail to minimize mechanical issues but after reading a few posts about losing hand, wrist or arm sensation for a while after touring the Great Divide I am now leaning towards switching the front fork to suspension.

With the changes in technology, model names from year to year which fork model or brand would be the most reliable or least likely to have problems in this type of tour?
