thanks for the replies..
took a drive out to Cabelas last night and looked at the new stove offerings...zoinks. they do appear to be more cheaply made than in the past..
As far as rebuilding, time does not allow that right now. there is a ton of rust on the suitcase so it needs to be sanded and repainted (is there even a coleman green??), and that is a project for another day.
In the meantime I'll probably seek out an older 425...ive seen a few that are NOS from the 70s...pricey, but around the same price as a new stove.
Also, whats up with the BTU rating on these? The coleman website lists the current generation as 14,000 BTU total, while references for older units list 21,000 BTUs with one burner, or when using both, 11,500 BTUs on the main and 9,500 BTUs on the auxiliary.
