Out in my area, Marlins are often less expensive than Winchesters, but not always. The other day brought up a Win 94 in 32 WS for $625, meanwhile a rusty Marlin 1894 was priced at $812, and a 444 was over $700.
It's true that new Miroku guns are pricey, but Marlin offers some new models that price over $1,000 retail. I was perusing the local ads, and a guy was selling his used Marlin 1894 for $1,000 firm.
My best guess is that the word is out concerning the desirability of the pre- Rem guns, and those that have them demand high dollar amounts, at least around here.
In general, the only Winchester 94s that consistently bring the lowest figures are those made from 1964-1980. Miroku guns consistently command twice to three times that price, of course this is assuming excellent overall condition. I can find Winchester 94s in that 64-80 time slot that are still good deals, work and shoot just fine, and cost less than a comparable pre-Rem Marlin.
