Well, it depends on what you mean.

In terms of currently available at retail outlets, some of the pricier ones are:

Brunton Vapor All Fuel MSRP $225
Jetboil Helios Guide MSRP $200
Optimus Hiker Plus MSRP $200

Primus Omnifuel MSRP $160
MSR Reactor MSRP $160

Optimus Nova/Nova+ MSRP $150
Jetboil Helios MSRP $150
Soto Muka MSRP $150
MSR XGK EX MSRP $150

Notice some clustering on the prices? Interesting, isn't it?

If you're talking about collector's items, the sky really is the limit. An Optimus 9 will fetch a couple *thousand* dollars.
