Thanks. I've been thinking about getting a remote gas stove, maybe primus express spider (mostly due to local availability) for the times when my pocket rocket don't work well, and I don't want to drag the omnifuel along. 
 The Omnifuel does of course make a good remote canister set up.    
 
  Although the Omnifuel does not have a pre-heat loop per se, I'll let you in on a little secret:  any stove capable of burning liquid fuel is capable of operating in liquid feed mode (provided that you can hook it up to a canister).  If a stove has the ability to vaporize a heavy fuel like kerosene, it's for darn sure it can vaporize liquefied gas.
The Omnifuel is truly a cool stove.  In weather above 40F/4C, just run it as a regular remote canister stove.  In weather from 0F/-18C to 40F/4C, run it in inverted canister (liquid feed) mode.  In weather below 0F/-18C, run it on liquid fuel.  Of course, any mode that handles colder weather can be employed in warmer weather; it's just that the warmer weather modes are more convenient.
On the other hand, I really don't need another hole in my wallet... 
 That's one of the reasons I reviewed the Rapidfire.  It's a) remote and b) has a pre-heat loop (which allows for liquid feed mode), but 
it's affordable.  I picked one up for less than $30.00 recently.
